Hi guys and gals,

need some help with my line :) Lately, when I've been driving, I get a sharp squeeling sound when I brake. I would need to brake it hard, for the squeeling sound to stop. Anybody know whats wrong, and how it can be fixed? Maybe, use some grease or something? :Paranoid:

Thanks, any feedbacks would be sweet! :P

You may find that your pads have not worn evenly (or you may have sanded them back) and when you apply light pressure the full face of the pad isn't touching the rotor so it squeels (this is what I was told by a reputable brake mechanic in sydney). I get a similar noise on very few occassions, if I softly press the pedal I get a gentle squeeze but if I stand on it then it brakes like it should and without squeel.

You may also want to take ur wheel off and make sure the little shims are in place.

Knowing absolutely nothing at all about cars, could it be his castor rod bushes that have worn out?

My mechanic replaced mine because they were wearing out and asked me if i had noticed a thunk noise when stopping.

If it makes that clunk noise after you have just finished turning a series of corners it could be worn/wearing wheel bearings causing the caliper/rotor to move and then when you apply brake pressure it has to push everything back into place.

Where can you get some wheel bearings for a R33?

I get some small clunking when I'm turning and braking at slow speeds, I was thinking it was my caster bushes, it clunks abit when you are going straight and over a few bumps as well.

My brakes don't squeal when I'm going forward but they squeal like a b!tch when I'm going backwards.:Oops:

RB74's are bendix ultimates rite?? mine dont squeel at all under normal breakin, only under really light breakin and of course reverse...hehe

RB74's are NOT Bendix and they are NOT DBA pads they are www.racebrakes.com.au pads. Bendix pads are designed for the daily driven Falcadores where as the RB74's are designed for the performance/track cars.

I put on a new set of Ultimates on mine a few weeks ago, and followed the 'bedding instructions' as per this site somewhere. I also have new wheel bearings.

They squeel under light braking, my old pads never squeeled.

The only difference I noticed between the new and old pads was that the ultimates only had metallic 'wings' on 2 of the 4 pads at the bottom, anyone know what these 'wings' are?

My stock pads & ultimates looked both the same. 2 of the 4 pads only had metal wings. As do the Maxi-stops I am currently running.

Did you remember to remove the shims from the origional pads & put them on the new?

Its easy to miss especially when the old pads are covered in lots of pad dust.

My ultimates never squeeked. The new el' cheapo Maxi-Stops ($26 an axle) don't feel anywhere near as nice, produce 1/8th the dust & squeel slightly after being pushed hard.

My pads didn't squeal until I had rear camber adjusters put in and the mechanic got the grease on the rear right brake disc. The front right brake now squeals. I think it got overheated having to cope with more braking as a result, probably just need right front machined again.

When I very very lightly touch the brakes the squeal is intermittent as the wheel turns it is only in one spot. Uneven disc? Perhaps carbonite build up? Can you see carbonite build up?

Would it be advisable to try putting some grease into the shims first or go straight for disc machining?

Would the grease on rear right disc wear off or will I need to use some brake cleaner or something to make sure it doesn't come back?

RB74's are very abrasive. 5 times as much I am told to Galver 1105's which stop real well, much better than ultimates.

Utimates are very very dirty and sqeal like a freight train, went deaf for a day due to the noise after 5 hours of driving, and to keep your wheels clean with Ultimates requires washing every day instead of once a week.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      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.
