For info, I've been slating trade club pads on here for years. The ones that come in the disc pad set. They squeal and give a very dead feel at the pedal. Or at least the ones from my dealer do.

TB, due to his crippleness, asked me to pick up a trade club disc pad set for him, and I fitted them for him. I refuse to use copper slip on brakes as you all know, no doubt, so TB applied his own copper slip where he wanted it. On the back and edges if the pad backing. All fitted job done.

Next thing, we get a thread on here. TB moaning about brake squeal and a dead pedal feel. Now TB can be a retard in certain areas. The state if his tyres seems beyond his understanding for instance, we all have our weak points. But I'm fairly sure he is capable of applying copper slip where he wants it, however fruitless an exercise that may. But if ever there was proof needed that copper slip is not a cure for brake sqeal, then that is it. Regardless of him admitting it or not.

I do agree with Andy Bedantic that the edges are a key area, and oe pads have shims that cover that area separating the pad metal from the caliper and stopping resonance. How anyone expects copper slip to last, not be forced aside by massive hydraulic pressure, survive all weathers and detergents AND stop brake sqeal and the resonance that causes it is beyond me.

But I guess just because somebody "always uses it" means that must be the cure, right? Maybe TB should rub it his spine, it will fix that as well. ;D although strawberry jam sales dept might come up with a reason why that might work better.

If you want to prove copper slip works, show me pads that squeal. Apply copper slip, and if the squeal us still gone in a fortnights time, then I "might" believe you.

Fact is, it didn't stop TB's from sqealing. Nothing said on here is ever going to change that.

 ;D they do grind down a bit once they hit the metal .

I always use copper grease, never, ever had squeaky brakes before this set. Guess who fitted them ;D

You have copper slip on your pads, they squeak like buggery.
I have no copper slip on my pads, as it has no place on braking systems, and they don't squeal. Prosecution rests. ;D
The common demoninator on squealy TC pads is you ::)

Moaning at gayboy aside, I do wonder if there is a pattern. Being serious for a while...

Never had squeals before, gayboy says every time he's used TC pads he has.  Upon questioning, he thinks all his TC pads have been ones that have been supplied with discs.

I can't, hand on my heart, say I've ever used pads from the disc and pad sets - usually other members have needed them more desperately than I have.  So this may be the first set of pads that have been supplied like that.

And guess what? Whilst they stop the car, they are lifeless, with no feedback. And squeal like a pig.


Will find out soon, I need to replace these pads soon, going by mileage - they're about 4k in now...

I have also noticed that the pad friction material shows quite heavy cracks across the surface.
TheBoy, I would suggest changing them sooner rather than later.

I have had various theory's, but never really fully accepted that there are two sorts of trade club pads available. Given Kevs experience with pad material braking off, and your heavy on brakes... I think a quick trip to the dealer is in order.

So do yours squeal in any braking direction, as mine only do it when braking to stop after reversing ...im going to wipe off all the coppa slip and re fit them then see if it makes any difference before buying new pads  :)

The disc's and pads on mine are from the TC disc and pad set and do not squeal. They have covered about six thousand miles with no issue. IIRC they have stick on shims, not the wrap around one's. I will admit that the best pads for sharpness were the one's originally fitted when the car was new. Any replacements since have given a 'hmm, this could be interesting' feel when urgently needed.  ::)

On a side note, I have never seen such a large leading/trailing edge as on TC pads. The contact face is seriously reduced by such a huge camber.  :-\

The set I gave you were from a Tradeclub set, not sure if they ever found their way onto either of your cars.

How do you know they squealed at all? If they squealed and applied cs to stop the squeal, and keep it stopped, them you'd have something.

IME the ONLY way to stop squeal properly is fit shims on all pads.

I've had a spare set here for a couple of weeks, as they must be getting down a bit. Just need to find time/strength to do it.
