Technical Sqeaking Brakes1

[revolution]

Can anyone help me? I have owned my 20VT since Jan this year and have recently had the brakes constantly sqeak at me! I have had the pads and discs changed but that hasn't made the slightest difference. It occurs on every journey and the longer the journey, the worse the problem gets. I had a friend with the same problem on his coupe after he changed the pads and discs on his and the noise went after some six months. I don't think I can take the embarressment of the sqeak much longer driving such a nice car. Any suggestions what the problem might be and how to resolve it?

common problem with the brembos. hotter they get, worse they are. its something i live with, but try cleaning the caliper slider mechanicals. you can fit aftermarket anti squeal shims. these stick to the pads. alot of squeal is a build up of brake dust, so give it a good clean. make sure sliders are working perfectly especially at front. indeed, mine are due to be done asap as they are getting worse!!!

Don't forget a dab of copper grease..

It is a common problem on all coupe's my one does it when the brakes get warm. I also followed another coupe today back from work and the brakes were the same on that. On mine (16VT) it comes from the back brakes and I think the one I followed did also, but that was a 20VT.

Mine did squeal like a b*tch for six months, but they've since quietened down. You can get anti-squeal shims for £20 that may or not work. Also you can slow down from 100 to 30 quite hard (but without triggering the ABS) for three times in a row, which apparently can cure or help the problem.

I wouldn't break like that too often as when the break fade kicks in. When the disks are glowing red the break fluid is boiling, and the pads are smoking. You will find you have no breaks. The pedal will touch the floor and it wont stop.


Squeaking breaks could be caused by sticking pistons in the calipers, or the break cable too tight. check also the break brackets are free of surface rust & grease the assemblely The thing is when a garage fits breaks. They don't take the time to free sticking pistons in the calipers. When the break peddle is depressed you should visually see the piston move back if they are operating smoothly. Just don't pump the piston out of the calipers when checking

I read a site somewhere that detailed the correct way to wear pads in. Bet I couldn't find it now. Basically gave speeds and amounts of braking and how many times to get them worn in correctly.

when new pads are fitted, you must not brake hard or hold your brakes on for approx 50 miles until they are bedded in[should not hold on brakes anyway, bad driving]. if you start braking from new hard, you will glaze the pads, and they will start squealing!
what i tend to do when fitting pads, is rough the surface up with some emery/wet&dry, chamfer the metal edges and spot them with copagrease. make sure the caliper is as clean as possible wher the pads run in and out this stops the squeals and reduces the chances of the pads sticking.

With all due respect dude, I know what causes the squealing on the coupe's brembos and how to cure that. Your brakes WILL NOT be shot after some high speed braking, unless you are driving a train! this method is proven after years of results on Fccuk.

All cars probably will suffer the same problems with with breaking systems over time. The pistons in the calipers do get lazy and tend not to move as freely as they once did. The coupe is not my car I'm PUNTO man. But surly the breaks squeak du to them binding slightly....??? The only thing heavy breaking at high speed like that continuously. In my eyes would do is ware down the pads & dangerously overheat the breaking system. Although the heat may have the effect of freeing the pistons slightly, and the ware on the pads would make them no longer bind. After high speed breaking the breaks would not be shot.. Dependant on how hard & at what kind of high speeds. You just wouldn't have any for a while when they over heat, believe me I know first hand

Thans for the info, I am now booked in at a garage for a brake check up and will put forward all your comments and advice to them. Hopefully my brakes will be sorted by the end of next week. If the brakes stop sqeaking, I will post what the problem was, although it may be a combination of a few things by some comments.
