Megane II Disc Brake Squeal?
Has anyone yet tried to pull the caliper pistons out, grease the piston sides, (Correct grease type please) refit them, bleed the system and then refit the pads using copaslip grease and anti-squeal shims?
Does this work on the Megane?
Answers:
Used to work for Renault and most of them gave problems with brake squeal.On no account put coppaslip on the surfaces between the piston and the caliper as this will damage the piston seals. Only use clean brake fluid. We used to use an anti seize grease on the rear of the pad where it hits the piston but it is important to put this also at the top and bottom of the pads where they sit in the caliper. The grease we used was an aluminium based item, similar to coppaslip but stickier. Even when the same car returned to have the pads replaced again, this stuff was as fresh as the 1st time. Are you sure that the squeal is coming from the front as non-asbestos rear brake shoes are very dusty and this also causes a bad squeal. Usually the drums need removed and cleaned and a little anti seize grease applied between the backplate and the point where the brake shoe touches it.
Are u mad dont put grease near brake pistons..add anti squeel shim and apply copper brake paste.problem sorted.
Copper brake grease on all of the moving and mating parts. Just don't get it on the disk/drum/pad surfaces.
i don't think that a grease should be used on the pistons, but brake fluid instead.
copperease has always worked to stop squealing if you put some on the back of the pads
it might just be an un-fixable attribute of that particular car, which renault may have known about after (or even before) its release, but didn't consider it important enough for a recall and refit.
That will not work, in fact it will just cause the problem with the brake dust on your front wheels to become like a thick syrup..be carefull. I havenot heard of a fix for the lifetime of the vehicle, only a spray treatment every 6 to 10 days depending on driving habits. While searching though stay away from the thicker lubricants and use the thinner ones..good luck.
My dealer (Swan Renault in Worthing) sorted it on mine during the first service, and it hasn't returned since (20,000 miles later).
Not sure what they did, though.
