hey,

i changed my brakes pads (front and rears) to bendix ultimates less than a week ago and had all my discs machined. Now they are sqealing badly every time i brake. Is this just the pads wearing in, or is something not right?

Thanks

Anton

No its right. Thats what they do. Mine squeal as well, mainly under light braking, but you've got to expect it with ultimates. Ultimates don't need bedding in, they come pre-bedded.

You can put brake goo on the back of the pads and shims to stop it from chattering on the piston, but I tried this and I lost a lot of brake pedal feel, the pedal went squishy/soft. Me not like, so I removed it.

If its squealing between the pad and the disc, there is a pressure pack stuff you can spray on the disc. You can pick it up from a repco store or something of the like.

If your like me, just put up with it. At least when it squeals it reminds you that you've got good pads. Don't worry about it when people look at you because of your brakes.

cheers Keymaker, ye i guess ill just have to put up with it. ill go to autobarn or repco and see what theyve got. the mechanic had another look at it and said its all fine but if i cant tolerate it, contact bendix and let them hear it and theyll supply new pads. anyone gone down this route and had success with new ones?

Thats a lil concerning....i never associated squeaky brakes as being a good thing....not questioning you, but can anyone else who runs Ultimates confirm this is the case and in general if squeaky brakes are ok.

Mine puts out two types of squealing. One is the high pitch squeal, the other is the really loud screech. It doesn't happen all the time. For most of the time they put out the high pitch squeal which is pretty bearable.

Sometimes they don't make a noise at all. It's much of a muchness really. If it starts to screech really loud, I'll drag that sound out as long as possible, it's funny to see the expressions on peoples faces :(

i've got bendix ultimates on the fronts, and shes been squealing under light braking load even with the old pads.

the discs are fine, so i've learnt to put up with it.

the first month or 2 was intense squealing, but over time it does it less.

hope that helps :(

Doesnt matter what pads u run they should never squeal or or screech.

I suggest taking out the pads and cleaning out the calipers, making sure the pads are wearing even (uneven means a stuck or faulty caliper piston) then scuff the pads a little (with some sand paper)

reinstall them with shims, and copper grease and then bed them in as per all pads need to be done.

Do this and u will never have noisy brakes.

thanks for the help fellas. Hopefully, Dave as you say, it will reduce in time

alot of this going around at the moment. alot of people have had these in before without squealing. I have heard a rumour that there is a bad batch of pads causing this. could be just a rumour or there could be some truth to it. probably best to try contacting bendix about it and mention that this is occurring on alot of cars at the moment.

Thats really strange. I've tried with and without antisqueel shims, with pbr goo and without. All combinations.

Absolutely no difference to pedal feel but a massive improvement in squeel; especially with light braking.

I found with the Ultimates if I gave it a hard run through the hills the pads would squeel a tad just before I came to a stop then with softer driving it would slowly go away.

Back to the pedal going soft/squishy. Thats definitely not right; I really think you must of had another issue going on there that was rectified when you pulled the pads out.

My pedal is solid and easy to lock the wheels; never does it require lots of pedal travel to lock the tyres.

I've only ran 1 set of Ultimates.

Never again; too much brake dust thats also a pain in the arse to remove; short pad life; rip the crap out of the rotors and squeel on light braking after a hard run (even though it was greatly reduced with shims and goo).

I'm currently running Ferodo's. Excellent pad, do dust up a tad but it washes off easily with a spray of the hose. :D

Next set of street pads i'm going to try is Lucus/TRW. Apparently pretty damn good pads that can take a little track work also.

there are also the wear indicators .. sometimes when mechanics put the pads on they wont bother to put these in properly and will cause them to vibrate and make a squealing noise.. sorry for the bad description i dont know too much about brakes.

Ultimates don't need bedding in, they come pre-bedded.

I really REALLY wish people would stop posting bullshit on here as "fact".

I suggest you all read this article:

http://www.zeckhausen.com/bedding_in_brakes.htm

& consider very closely this statement:

"Simply stated, bed-in is the process of depositing an even layer of brake pad material, or transfer layer, on the rubbing surface of the rotor disc. That's it. End of discussion........."

So with that in mind can you please explain how ANY pad can come "Pre-bedded"??????

Prior to fitting my pads I spoke to a mech and he said to use silastic/silicon for the anti squeal goo because that's all that stuff is.

When I did fit my pads I applied the silicon. A seal in the master cylinder died as I fitted the pads due to pushing the fluid back up the lines and through the cylinder. Now that made the pedal really squishy to the point it would just hit the floor.

After I got the seals replaced the and had the master cylinder reconditioned the pedal was still really squishy, so I took the pads back out and took all the silicon off the back of the pads and shims etc and it was instantly better pedal feel. Maybe I over applied the silicon, but I didn't think so, it was just a smear.

OK I admit I shouldn't of used the word Pre-Bedded as that changes the meaning of everything.

I should of said Pre-Conditioned.

This is straight from the Bendix Horses mouth.

Ultimate pads are recommended for fitment to front and rear, to maintain balanced driving for sports, performance and prestige vehicles. There is a reference to suit most high performance European, Japanese and Australian cars and they are pre-conditioned during manufacture so there is no bedding-in required.

Unless bendix is lying to us.....

I had my 34's front discs machined and Bendix Ultimates put on about 3 weeks ago. Mine are also squealing. I took it back to the mechanic who fitted them and they machined the "glaze" off the pads, but 2 days later, they were squealing again. The mechanic suggested that i do hard braking to try to wear them in better, however it's not like i can in peak hour traffic every day. And not to mention the amount of brake dust coming off them is terrible!

I'll be changing the pads to a different (more expensive) brand when my next service is due. I really can't stand the squealing.

I've been recommended EBC or Endless to try...

But bendix is sooo cheap! hahaha I'm a budget person. I don't find dust much of a problem. I mean by the time the mags are so dusty, the whole car usually needs a wash anyway. Just wash them when you was the car. But then again, my mags are black. And squealing, who cares...? just turn the stereo up so you can't hear it ;)

I'd say the silicon was part of the problem. Pbr glue I use resembled grease.

Don't use silicon, what a mess it would make.

Funny that. I asked the mech about some copper grease or something and said noooo don't use any sort of grease stuff. He was saying that the silicon would match the shape of the piston once it pushes onto it and stop it from vibrating. I used gasket silicon so it was pretty easy to remove. He also reckons that the red or orange brake goo is just coloured silicon too......? hmmmm.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
