Brakes obtained so time to fit. The numpty at the dealer gives me a set of pads for the rear, and when told their error tells me the front pads are £40 dearer

Pointing out to the div that on my receipt, it said front pads, and he could fekk off, saw a £40 saving

Most brakes are much of a muchness, so its a fairly universal procedure.

First, undo the M/C cap.



Once the wheels are off , this is the view.



Undo the 2 bolts at the rear of the caliper (18mm)


Release rattle clip


Pull caliper away, and secure with wire/tie



Undo grub screw on disc



Remove disc.





This is the time to clean the hub face with a wire brush.

New disc.



Old/New




You can see how they balance the disc here.



Old/New pads



Pads fitted to caliper.



Slide caliper on.



Refit rattle clip.



Bolt the caliper up, after putting some Loctite Thread Seal on the bolts.

Caliper pins were treated to the faintest smear of copper grease as well.

Tools required, 18mm socket/ratchet.
3mm hex head
Bit of wire.



Not a good time to find out D3 rims don't fit with new pads in the calipers



A couple of 3mm spacers later, and they're on, but are coming off as soon as the pads have worn a bit.

Total time, 20 minutes a side, once the wheels are off.

Total cost £285.

Its in for a big service in a couple of weeks, fekkers are going to be gutted when they can't bolt me up for new brakes

Thanks for the post, I think I'll change mine myself when they need changing.

Did your discs need replacing? Couldn't you have just changed the pads?

Did your discs need replacing?

About 10k left, but a pad sacrafice taken into account, and while the wheels were off etc.

Great write up Roofer, good range of photo's, I'm amazed how small the front pad are, is it easy to reset the OBC as to the "range left on pads" ?

Roofer, Great write up we need more of these kind of threads.

Nice write up - thanks.

Out of interest, how many miles were on the old pads and discs?

£95 ish + vat each. The lot was £285 with pads but they incorrectly supplied pads, so should have been £300 ish.

Great write-up Roofer. I always change pads and discs myself too.
