Brake Screech

Hey everyone,

Here's the story...

I bought a full set of rda slotted and ebc red stuff back in august. i had them professionally installed and bed-in by my local mechanic and immediately they were exhibiting some unusual brake squeal.

it was unusual in that, the harder i pressed the brakes, the louder the noise became. regardless of how warm or hot the brakes got the screech was ever present. in fact when the pads got hotter the noise seemed to get louder! the only silence I had was on the first few brakes in the morning after the car had been sleeping over night.

After searching on the forums I tried using some of that red brake goo, but that did exactly diddly squat. the noise was still there with no change.

I took the car to a few performance workshops, and they all said it was because of my combination of rda rotors and ebc redstuff. both being hard, the pads weren't able to "bite" into the rotor and so they slipped (vibrated) across and made the noise. all the workshops recommended that if I put some ebc greenstuff instead it'd be all sweet and dandy.

So...

just recently i got some green stuff (again with professional installation and bed in). much to my dismay the noise is still there, albeit with different behaviour.

this time if i run the car through a series of hard braking (60 to 10 kmh about 7 times), the pads go completely silent... until they cool (even after a few minutes) where the noise slowly increases as the pads cool further.

also, at normal street driving temperatures, the pads seem to squeak (slightly) less if i press hard. but they're still pretty damn loud either way, sometimes almost deafening.

I've run out of ideas, and moreover this squeaking is making me DREAD the thought of driving my car ;). something no skyline owner should have to experience!

can anybody PLEASE offer any suggestions? if you live in melbourne and think you might have a solution I'd be more than happy to meet you somewhere and pop ur ear drums for u (yes it really is that bad sometimes) if you can help me fix my problem you WILL be rewarded!. I'm getting pretty desperate and i fear my sanity is fast deteriorating :wave:

the squealing is a resonance in the disc making it act like a bell. try descaling the hubs, backs of the wheels, and the disc mounting surfaces. its been known to eliminate brake noise. also try using some el cheapo pads like Ferodo XL. the red stuff squealing doesn't surprise me, way too hard for the road. for that matter unless you're always running the greenstuff at optimum temp it won't be coating the disc with compound and will also be more prone to squeal.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
