Replacing rear pads ........

[SimonV8ster]

Having got the old pads out I'm trying to wind the piston back in but not a lot seems to be happening ?? The bible says to turn clockwise, this sound right ?? If nothing seems to be happening what does this suggest ??

Clockwise is right. The piston needs to be pushed and turned at the same time. If you're trying to do this without the proper tool stop now, buy the tool from any decent motorfactor for £10, and you'll find it's an absolute doddle.

What Peter says & remember to line up the pip on the brake pad backing with the cross on the piston,otherwise the piston will not sit on the backing properly causing the piston to jam,i have seen this more times than i care to remember,spongy brakes and shit handbake you betcha.

Thats interesting but not sure what you mean.
Any chance of expanding on that one please

Thanks Guys, I've stopped now, reliased it was a no go without the correct tool. !!

The 'pip' is a piece that protudes from the back of the brake pad and slots into a hole in the face of the piston, to stop it shruddering around I guess ?

Right, now I've bought the right tool (and yes it was a piece of p*ss after that) and I've wound the piston back in. Pads are back in and the caliper is back on. There is a small amount of play between the pads and the disc, does just starting to use them mean the piston comes back and finds its 'natural' place ?? Or do I have to do something more ??

[VerySideways]

Drive it - use the brakes - careful the first time as there may be more dead pedal than normal...

[GreenV8S]

After you've done one side, pump the pedal a few times until it goes firm. This will seat the pads back against the disc. If you forget to do this, two things are likely to happen. The first is that you may find the reservoir overflows when you push back the next piston. The second is that the pedal will go to the floor the first time you try to use the brakes.

No its to stop the piston rotating which would cause the handbrake mechanism to fail,when you have fitted the pads carry out short strokes of the pedal to push the pistons out to meet the new pads,otherwise you could damage your master cylinder if you stroke to the floor;eek:if you look thru the window on the calliper you can see the piston on the pad backing which says the pip as engaged.
