I tried to do that but they wont budge could the caliper be seized on? also i cant start the car at moment so could it be a build up of pressure behind the piston? may sound like a dumb question but i have never changed the front pads before.

Mirez Posted March 19, 2010 Report Posted March 19, 2010 The pressure should subside with the engine off, in theory you'd actually have more if the engine was running. There is a possibility thats its seized on but its somewhat unlikely, should just compress though - how are you doing it? Quote

I'd also recommend using the time you push the calipers back in as a brake bleed opportunity and release the bleed nipples to push the nasty old brake fluid out that way rather than back into the system.

ag-1982 Posted March 20, 2010 Author Report Posted March 20, 2010 thanks ill let you know how i get on Quote
ag-1982 Posted March 20, 2010 Author Report Posted March 20, 2010 I managed to get the front brakes fitted but now ive not no power onm acceleration sounds like something grinding from the back and the brake pedal goes straight to the floor and doesn't like stopping any suggestions will be greatly appreciated thanks Quote

Sounds like you need to bleed the brakes again if you havn't already done so, is this grinding noise there since you have replaced the rear pads? if so you need to recheck everything + make sure the disc back plate is not rubbing on the disc you may have inadvertantly bent it while removing/replacing caliper Quote
ag-1982 Posted March 20, 2010 Author Report Posted March 20, 2010 ok thankyou ill have a look in morning and let you know how i get on thanks again for the fast reples! Quote
