Replacing Rear brake disc

if the wheel isnt off yet hit the bolts with some plus gas every day for a few days while your waiting for the new disc


if you aint got a welder but have a blowtorch get some heat on those bolts then hit them with some plus gas /wd40 / thin oil and let them cool
and give them a good whack with a hammer to shock them (every little helps)


there is also the candle wax trick but hardly anyone has candles anymore
then its time to get out the shortest socket you have and a breaker bar - those fuckers are tighter than a ducks arse but not as waterproof

I wouldn't really do this if the bike's still being used, otherwise it's all gonna get rather dangerous with oil on the disc and pads!

The best place to squirt the Plusgas is to aim inside the hub where the open ends of the threaded holes are so it should be possible to keep it off the disc and pads. Spraying the heads of the screws won't get it where it's needed so it won't have much effect (other than on your braking, as you suggest).


I too need to get a disc off, Fortunately it's my spare wheel, but it's an original disc. I made one attempt earlier this year: liberal application of penetrating oil for weeks, warming the whole wheel over a gas ring until it was at 90º and then I attacked with the impact driver. Other than destroying the allen heads it achieved nothing.  :'(


I'll use the welder method next time.
My preference is to use Copaslip rather than threadlock on reassembly!
