PaulM Posted August 14, 2011 Report Share Posted August 14, 2011 Hi there I had exactly the same problem recently. One of the two sliding bolts had seized completely on mine. How I fixed it ; Ordered a refurb kit which contained two new caliper sliding bolts, rubber boots and grease. Took the pad holder off with the suck bolt in it. Clamped the pad holder carefully in a large bench vise then put a socket head on the stuck bolt. Applied some release compound (posh WD40 basically) and allowed to soak in for a few minutes. Used a wrench bar to turn the stuck bolt in place to break the corrosion. Once it had done three turns it started to move easier. Then using a hammer and blunt chisel started to whack the underside of the bolt head. It took ten minutes but between turning and whacking the bolt had moved enough to be removed. The bolt isn't threaded in place, it just sits in a hollow recess in the pad holder. Mine had corroded in place as the rubber boot had split at some point. Once removed it was an easy job to clean up the recess head and drop the new bolt in. I did change both bolts as two are supplied in the refurb kit. Got my refurb kit from Brakes International, cost about £20 with postage. Reference code BCF1377. Hope that helps! Paul M Link to comment Share on other sites More sharing options...
nthnmunky Posted August 14, 2011 Report Share Posted August 14, 2011 Push it back using an extension bar from a socket set. Put the smooth end of the socket extension bar in the middle of the piston that you're trying to push back then push against it, if the caliper is still off the car you can press it down with the bar on the floor for extra leverage! Claw hammer wedged in will also do it etc. Just requires a fair bit of force Topics merged. Try not to post the exact same thing in different areas if poss. It just leads to cluttered up threads and forums Hopefully you've got it sorted now Link to comment Share on other sites More sharing options...
c_jnz Posted August 14, 2011 Report Share Posted August 14, 2011 I always leave the old pads and discs on and use a lever between the two to push the piston back. Link to comment Share on other sites More sharing options...
Hoody Posted August 14, 2011 Author Report Share Posted August 14, 2011 sorry about the posts. just tryed what you said but its really stiff, do i need to take the brake hose off or do anything with the brake fluid? Link to comment Share on other sites More sharing options...
oMIKEYo Posted August 14, 2011 Report Share Posted August 14, 2011 Take the cap of under bonnet to release pressure. When you push them back make sure it doesn't over flow as you'll have no paint left. Get someone to stand and check Link to comment Share on other sites More sharing options...
nthnmunky Posted August 14, 2011 Report Share Posted August 14, 2011 It's going to be stiff, that's why I suggested pressing against the floor for extra purchase. It's difficult to move but it WILL press back Try harder lol. Link to comment Share on other sites More sharing options...

Gstraw Posted August 14, 2011 Report Share Posted August 14, 2011 yeah remove the brake fluid cap under the bonnet then i could move the piston almost by hand...very tough but its doable. if u leave the cap on then you can't lol. the pressure has to go somewhere Link to comment Share on other sites More sharing options...
