Brake squeal.
« on: 25 October 2011, 09:48:26 »
Put a new set of (OEM) pads on the other weekend and now I've got squealing brakes at 'normal' pedal pressure (if I push harder or gentler I can stop or reduce the squeal).

Any idea what could be causing it and, more importantly, how I can stop it?

Cheers,
Gaz

Trade club pads I take it? £14? ...oe are a lot more than that, and don't squeal.

Some might suggest copper slip on the backing, but it's a complete waist of time ime.

Well they came in a GM bag, from a Vx dealer!

I sort of took that as evidence enough!

Ahhh

GM do 2 pads.... known as TC (trade club) or OE (original Equipment)

the TC ones are about a tenner from memory.
the OE are about £90, and some say they perform better, fade less and create less dust,  The definately seem better made.

Which did you get?

Defo the former - I only paid c£15! From AndyC.

My driving style these days never makes brake fade a problem (too concerned with the cost of fuel to go booting it round the countryside!) - and if they make more dust I'll just have to visit the carwash more often!

It's the squealing I'd like to fix if poss!

we run both I have OE currently, she has TC, neither squeal.

I have had a set in the past that did squeal though, cured by replacing.

I do use copperslip on them.

If they don't get any better on their own (I know they do sometimes) I'll dollop some on.

I don't understand the need to file them tbh. The shamfers are already enormous on the ones I've seen. Are there different suppliers of tc pad I wonder, just slightly different ways of making them to the same spec. maybe...?
