davefly76 Posted October 21, 2012 Posted October 21, 2012 How were you planning on getting the bike to your new place if the wheel did turn?? Get a mate to help by lifting the front wheel off the ground and get the bike in to the back of a van. Quote

Mrbarry Posted October 21, 2012 Posted October 21, 2012 Can you get a skateboard under the front? Or a trolley of some sort? If not, wd40 and heat! Quote
megawatt Posted October 21, 2012 Posted October 21, 2012 If all else fails, undo the disc bolts? Quote
Fozzie Posted October 22, 2012 Posted October 22, 2012 I unseized an old bikes brakes recently,I undid the banjo and drained the brake fluid, relieving some pressure then took off the caliper. You should be able to get the caliper off it's main mounts, if they are seized or you've rounded them you narrow your options. Get an angle grinder and delicately grind a slot into the bolt head, then with your biggest flat head screwdriver try and twist. But use plenty of WD40 after the slot is cut. And if you dont have a angle grinder try to borrow one or use a hacksaw if the angle permits it.But try and get some heat and WD40 on it first Quote
Tango Posted October 22, 2012 Posted October 22, 2012 How about removing the front wheel.....or with a long hefty flat bladed screwdriver try to knock the pads of their backing by gently hammering the f*ck out of them......in a precision sort of way of course...... Quote
megawatt Posted October 22, 2012 Posted October 22, 2012 I was actually serious about removing the disc bolts! If pads are locked onto disc and you can't get them off, or remove caliper, if you can get an allen key in there, you can undo the disc bolts. Push bike forward or backwards to break the seal and the wheel will turn while the disc(s) stay still. Quote
skikman Posted October 22, 2012 Author Posted October 22, 2012 thanks folks.i put a flat head screwdriver between the pads and disc and taped it with a hammer.got it freed enough to push.wrecked the pads but they were probably f**ked anyway. Quote
Guest Posted October 23, 2012 Posted October 23, 2012 Undo bleed nipple to relieve hydraulic pressure (as previous poster mentioned), then hit the face of the calliper with a hide mallet (don't use metal-headed hammer otherwise you'll damage the alloy) - this should force the piston inward allowing the wheel to move.This has always worked for me - just remember you've got no front brake while moving the bike.

megawatt Posted October 23, 2012 Posted October 23, 2012 I think I know where your coming from , but hitting the caliper while it's bolted to the fork leg. May work on some calipers, but not all and may damage the disc carrier. Quote
oslin06 Posted October 28, 2012 Posted October 28, 2012 Hi Skikman, pity you did not list your location I was trying to see where you were with a view to coming to help you, but I have no idea where you are.keith Quote
