Peugeot 206 brake squeal
Hellfire - 17/4/07 at 10:52 AM

The Peugeot 206 apparently has an inherent design fault, in that the brakes squeal. The front discs/pads appear to be the culprits and it although it isn’t annoying I would like to be rid of it. Vehicle is currently fitted with OEM stuff and I am wondering if certain aftermarket pads or discs would prevent this. The discs are getting ready for replacing soon and I was considering getting some drilled/grooved discs in the hope that this will cure the problem, however, it would be rather expensive and seems a bit OTT, if it can be cured by using different pads. Unless that is, someone knows of a cheap source of grooved discs.

What actually causes the squeal and has anyone got any suggestions as to what will cure it, other than selling the car and buying something else!?

I worked at a stealers until 03, there used to be a superseded part no for some Tu petrol models. We also used to use an antisqueal compound on the back of the pads on some, as I remember. The dry weather makes them worse though. Some times chamfering the edges of the pads helps too.

What actually causes the squeal


Brake energy being dissipated through the suspension and brake structures excites the natural frequencies of said brake and suspension structures. Some of these frequencies are audible and some aren't.

It's always tested for and usually solved prior to release of the vehicle/braking system.

The main problem is making sure you cover all decel' rates (forward and reverse directions) with all vehicle shapes and options and brake pad materials.

Because this is extremely time consuming there's a certain amount of luck employed as well as a huge amount of test work - and still some situations can cause brake squeal.

The situation will never be perfect - but different pads may help or may provide other combinations that generate other noises - Sorry.

copper grease behind the pads usually sorts this, as does small bent springs pushing against the pads. But I like the grease more.

Copper slip is only a temporary fix. I'm looking for something a bit more permanent. If glazed pads are causing the squeal, I figured maybe grooved discs or softer pads may cure it?
