ive given up trying to source the problem on my own! so i thought i would turn to the all knowing forum!
i have replaced my rear brake pads and sensor, with EBC ultimax pads, one side (im not 100% sure which but probably the drivers side) has a very very annoying squeak, which can even continue when the brakes arent in use at all speeds?! i have re fitted both sides 3 times now with copper slip, a good clean and a proper caliper rewind tool, but i am still bemused why it is happening, its like the piston isnt returning enough to let the pads clear the disc.
my next attempt will be to rewind the pistons anticlockwise instead of clockwise, but im a bit fed up of faffing with them now!
any help would be massively appreciated.
i had thought of that, but the issue wasnt apparent before changing from some oem pads that were on the car when i bought it. and i cant think of anything i have done mechanically or driving wise to cause a warp?
the spring clips which attached the pad to the piston are quite difficult to get on and there is no easy way to check they are really in place, if they are not in place properly you could definitely get the sort of problems you are having
I had this when i replaced mine with mintex pads and new disc's, took it to a local garage and he said he's had quite a few problems with top brand pads squeeling. He cleaned them up and used bosch brake grease instead of copper grease and its now gone. Give it a try..
Secondly, put copper grease on the 'ends' of the pads where they 'sit inside' the caliper carrier. I didn't do this as I've never had to do it in years of brakes on Japanese cars - because all the Jap cars I've worked on have had metal bracket things that fit into the caliper carrier that the pads sit in.
And of course make sure you put copper grease on the back of the pads.
Mostly the reason squeaking brakes is low quality brake pads. Many car stores are offer low quality brake. The main reason for those pads is they are less in cost. If you want to quiet your brake quiet on breaking, you need to buy ceramic break pads. I know they are little costly but they are better in quality.
