Rear Discs & Pad Replacement
 

I just got a new MOT but there was an advisory that the rear discs are pitted and worn (which they are), so I intend to replace them

I had no problems with the front, but are there any special problems with the rear ones that I should be aware of, or are there any special tools needed?

Thanks .... Mike

The brake caliper bolts can sometimes be a pain to get out. Probably worth having some new ones on standby if you don't know the condition / ease of removal of the current ones.

You might find that the scope of the job increases as once you have the disc off you will have access to the handbrake shoes / mechanism which can be checked / cleaned / adjusted.

Yes, as above. I use a 'walled' hexagon ratchet spanner on the bolts, a 1/2" AF one (it's a better fit than 13mm) I tap the spanner with a mallet/hammer to start to undo the bolt. Overall, not a bad job to do.

Good evening Mike,
Rimmer Bros have a video showing the replacement of the rear discs and brake pads on a Rover75/ZT.
May be worth a view?
Regards David

I also did the front discs and pads before the rears.

I found on the fronts I could change the pads without unscrewing the sliding caliper pins from the caliper bracket, but on the rears I had to unscrew the pins. This is because there's less space to get the pads in as the disc isn't vented. I used a 7mm hex bit with a 3/8" drive made by Laser.

I gave the handbrake bits a good blow out and squirted the friction surfaces with brake cleaner, but everything looked OK and works fine.

Good luck

I found a 13mm crows foot spanner works well on the mounting bolts. New bolts advised.

I found it was a bit of a fiddle when fitting the shoes and springs back on but managed it in the end.

Little bit like one of those metal puzzles but easy if you know how.---:D

Sometimes the 13mm bolts can be rounded due to someone not using the right tool to remove them or they are stuck fast and round off.

These little slim shallow removal socket will get you out of trouble. ;)

few photos that may help ;)

I've got rounded out disk hex bolt any ideas of how to remove

A sharp centre punch needed. Mark a dot just in from the edge and then hit at an angle (for anti clockwise rotation) until it moves. A little shot of plus gas may help but don't drown the brake shoes/pads! Alternatively, score a screwdriver slot into it with a dremel.
