Changing front brake discs

Recommended Posts

This is quite an easy job, but made difficult by badly seized bolts that hold the caliper carrier to the hub carrier.

 

The problem is that the end of the bolts protrude out of the mounting holes, close to the disc, and so corrode badly, seizing them in! Add to that they are torqued up to 135Nm so end up being right buggers to get out!

 

It's best to apply some WD40/Plus Gas or similar the night before, at both ends of the bolts.

 

The only way I could free them off was by using a good socket on a ratchet handle, with a foot long bar on the end of that. But you must support the hub carrier from underneath with a trolley jack or block of wood, so that you efforts dont damage the suspension & steering alignment in any way!

 

Once they are off, clean the bolt threads up with a wire wheel attachment in a drill, or replace them if they are really bad. Refit with loads of copper grease, especially at the exposed thread end!

 

Hope this helps ppl comtemplating this " 1/2 hour " job! :wink:

The effort of undoing the bolts can actually bend the locating lugs on the hub, so that when you put it all back together the caliper is not centrally mounted over the disc which leads to all sorts of strange braking problems. A bit of heat and hammer will sort it out.
