Changing Brake Discs

(1/6) > >>

Homer:
Hi All,

I am thinking of changing my the Brake Discs on my disco this weekend.

Is this a big job?, how long should it take to do each corner and what do I have to remove to get the new ones on?
Also please take into account that I have limited space/facilities (I wll have to do it in the Car Park).
I have the service manuals on CD, but not being the most mechanically minded person on the planet I would appreciate your input before I start undoing any bolts!

Also should I consider renewing anything else while I am a it?

Or should I just hand over some cash and get someone to do it for me? (any volunteers? :lol: )


Thanks


Mark.

Did mine the other weekend.  Took about 45 mins per corner, but wasn't rushing.

Order of events (on a D2 anyway):
1) Remove wheel
2) Unbolt caliper and move it out of the way (taking care not to stretch the brake or ABS lines)
3) Remove old pads
4) Unbolt caliper carrier from hub (these bolts can be a bit tight) and remove
5) Remove screw holding disc to hub (had to use an impact driver on mine)
6) Remove old disc from hub (mine took some bashing with a 4lb lump hammer to shift it)
7) Clean everything up
8) Refit is the reverse of removal  :wink:

You'll need to push the pistons back into the caliper somehow.  I've got a tool that does this and makes it easy.  Worth getting one if you can.

Make sure you fit new pads with the new discs.

Good luck  :wink:

In what way? Mine is a '94 200TDi.

On a 200 & 300 Disco the process is:

1. Remove road wheel, after chocking the other wheels!!  :wink:
2. Remove brake pad retaining pins & break pads.
3. Remove the brake caliper, two bolts on the inside of the calliper. (You may have to undo the top swivel pin to allow the brakepipe to the calliper to move enough to get it clear of the disc. Once clear, replace the swivel pin & secure with one bolt to stop too much EP90/swivel grease from leaking from the bottom of the swivel.)
4. Remove rubber cap in the centre of the hub to reveal the end of the stub axle & remove circlip with spacer.
5. Undo the 6 flange retaining bolts and pull the flange clear.
6. Push back the locking tabs on the hub nut retaining washer and undo the hub nuts, there are two, outer is a locknut, inner to tention the wheel bearings.
7. Remove disc & wheel bearings from the stub axle, being careful not to getany dirt in the bearings.
8. On the back/inside of the disc there are 5 or 6 (can't remember) bolts that need to be removed to release the disc from the hub then remove the disc and clear any deposits from the hub ready for the new disc.
9. Reassemble, remembering to regrease the wheel bearings and tighten them to the correct setting. Everything else goes together in the reverse of how it came apart.
It's best to replace the rubber seal at the rear of the hub and have new locking washer for the wheelbearing nuts and a new gasket for the flange.

There are torque settings for the bolts on the disc, flange & calliper, so check on those. The whole job is described in the Haynes Manual.  

Hope that helps.  :D
