Bendix Ultimates + Machined Discs = Squealing?

Hey guys, another annoying thing... i just got all 4 discs machined and fitted brand new Bendix Ultimate pads all round... its pulling up perfectly now and I love the feel of the breaks... but the front drivers side squeals under medium braking... its so annoying! Even before i changed them it never ever squealed! I tried light breaking under throttle hoping to eliminate any debris but it stops for a while then comes back when the pads cool down…

I know most of you will say Bendix are crap but i have never had any issues with them in the past.. the spare parts guy recommended Lucas Brake Pads... but i stuck to the Bendix

Any suggestions?

Regards,

Sarkis

Hi there. I have the same problem on the front with the bendix

But only under light braking when it is raining. I recently had the

back done and asked why this happened. The guy said at some

point in time for about 8 months bendix pads that were made

in this period had this fault (nothing to do with the performance

of the pad). He said they now have fixed the problem. Not sure

if this true tho. Im still running them and they work well. Hope

this helps. :D

I have found the exact same issue on new rotors with Bendix ultimates on my R32. I spent a lot of time and consequently money trying to stop this squeeling. I have installed a shim kit etc but it's still squeeling.

Basically it seems that Bendix ultimates have changed somehow (or they manufactured SOME that were bad) and are now a pretty annoying brake pad. I'm trying to find a suitable replacement and will be asking Bendix compensate me for these faulty pads.

my experience

1. clean rotors with brake cleaner....really well

2. use shims on pads

3. use stop squeel glue on the pads

4. clean pads with brake cleaner if they get dirty too.

always be careful where you put you greasy fingers.

seems to be working well with dba rotor and utimates.....i did have them squeeling on my last brake change, so i pulled them apart....and did the above again....and been really good since.

Are the discs still above minimum thickness? I had trouble with my R33 fronts that were screaming with Bendix brakes. Tried everthing. When I took them off and was about to have them machined we found they were a long way under minimum.

By the book, there is about 2-3 mm between new and not to be machined. Put some DBA slotteds on. Screaming gone.

Ive had bendix ultimates on my fronts... I have done everything.. I'm not too bothered by it. I would never by ultimates again.. just a waste of money really.. could have spent my 80 bux better elsewhere..

By the way, the pads just glaze the rotors pretty much straight away, so your gonna get squeels, and yes i have used disc brake quiet to no avail. bendix advances all the way.. less dust, less noise, less eating away at my prescious rotors which are now way undersize.. oh well

I had nasty squeels even at low speeds and light braking.

Roughing up the pads works well (so there is no smooth flat spots where the dust gets caught)

I got a hack saw out and put light score marks diagonally along the pad.

haven't had the problem since.

well...

wont have the problem until the pads wear down so theres no score marks at least

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
