Dean3988 Posted December 4, 2009 Share Posted December 4, 2009 Got dot on the drive jacked up trying to replace the brake pads... but there are two bolts holding the caliper onto the car... the top bolt has come undone but the bottom one will not move... it has been slightly rounded off so a 13mm will no longer go on without slipping.. Have tried using a half inch... no luck and then using a 12mm but that still didnt work... Theres no room to fit any type of pliers of what have you in there so what can we do?!

RickyBobby Posted December 4, 2009 Share Posted December 4, 2009 Is there any way you can heat the bolt up? May help loosen it a bit... Quote Link to comment Share on other sites More sharing options...

If you get a socket with plenty of splines in it 13mm or if that slips bang a12 mm on and it will work,and heat it up if possible first ;) Quote Link to comment Share on other sites More sharing options...
Chris Ecc Posted December 4, 2009 Share Posted December 4, 2009 Is there any way you can heat the bolt up? May help loosen it a bit... that would make it stiffer the bolt would expand Best bet i think mate is to put it back together take it to a garage get them to do it and act like you never touched it Quote Link to comment Share on other sites More sharing options...

Yeap.. Wheels were on full lock.. its just the way the calipers are... Theres not much room to fit a wrench in... Anyway.. managed to get the bolt out by hammering on a 12mm and then a shiteee load of man power haha Quote Link to comment Share on other sites More sharing options...
