Brake discs
« on: 05 December 2003, 22:27 »
Looks like it not too long off before I need to change my brake discs, front and rear.  Is this something I can do myself (not got too much car knowledge) or is it a garage job, if its the later does anyone know what sort of price I should expect to pay.  Also can assume that a brake disc is a brake disc or (and I expect this to be the case) is life just not that simple?

My guess is that it shouldn't be too hard.. Not actually done it myself on a golf, but the disc changes I did to my vectra were a piece of pee pee.....

Defnitely wirth considering in my opinion....  Just need to be careful on the rear discs setting up the pistons and handbrake linkage.

Sure there will be others more able to give accurate advice very soon.

I havnt tried this before but....

Take the wheel off,
Unbolt the calliper,
Undo the phillips screw that holds the disk on.

Not too sure.

As your changing your disks I would consider changing you pads aswel.

Price (vented) mk2 Gti disks, fronts- about ?45 each ???

Back disks are a little more involved but still a piece of p1ss to change. just don't let the calipers hang on the rubber hoses when you remove them  like I have seen some people do in the past.

forgot to mention also. If you are buying new discs you can usually find drilled ones for about 50 quid a pair in the golf mags.  :) Depending on how hard you cane it good quality pads are a must as well. I have used EBC Green Stuff pads for some time now on performance cars and have never had a prob with fade or the pads glazing over. they also don't generate alot of dust so it keeps the alloys looking good.

Front discs are quite easy but get an impact driver to get the crosshead screw out. Rear discs are a little bit more complicated as everyone has forgot to mention the wheel bearing is housed in the rear disc hub. To do the rear discs you will need a new bearing kit and probably a special tool to wind the piston back in(available from halfords). Press the new bearing shells in with the old shells and a bit of wood, then put the the new bearings in. Make sure you use plenty of grease.
If you are not fimiliar with doing the work then maybe it might be better to do the fronts and get someone else to do the rears.

Stop me if I am wrong here lads but you also need to make sure you clean the hub very well to make sure the new disks sit completely flat, otherwise they will warp or shake the steering wheel under braking !!

Good point '6 didn't think about the bearings. One more thing that sticks out in my mind. When you wind the pistons back into the caliper on the rear and get everythiong back together and before you think about starting the car pump the brakes about 50 times to readjust the rear calipers if you do this with the engine running the assist from the power brakes can lock the backs tight on. :) we found this out on my mates car a few months back.
