Front break discs

Don't think mine will pass the MOT (October), so need a set by then.


(Anyone changed any before? Old ones come off ok?)

I you have proper tools it's very easy, dodgy chinese tools from the local market and you will be in a world of hurt.


I have just changed mine, I heated each bolt, with a soldering iron, to help loosen the thread lock then used an impact driver to give it a bit of shock tactics.

I heated each bolt, with a soldering iron,

With the amount of metal in that location there is no way a SI imparted enough heat, assuming you used a 21/50w mains unit...?

Not sure what the wattage is, but its an old one I borrowed of my dad (so it will be from the 50's) it has about an inch wide chisel tip. It is the type metal workers would use for tinning, not a little hobby thing from B&Q used for soldering wires etc . In the past I have used a  gas torch to get some heat in.


My main point is not to use cheap tools that can damage the bolt and using an impact driver helps too

I would recommend using a good quality set of Allen keys with a long shaft for good leverage and make sure the head of the Allen  bolts are clear of any dirt - this will ensure you get the key in as far as possible for good purchase and to reduce the risk of rounding the head of the allen bolt. These bolts are normally thread locked and torqued, so can be a bit stubborn to shift.

I always wrap a hand towel or cloth around the Allen Key end as the "snap" and shock that's transferred to your fingers when these bolts loosen can be painful - you have been warned !!

Best of luck!

Well, lets hope they come out. the ones on the rear disc didn't. Well, they did in the end but they took the thread with them and all ended up needing heli-coils.
