Went to do my rear discs and pads today and I've read up how to do it etc. From what I've read the calliper bolts should be 7mm Allen bolts but I think mine a 13mm normal bolts. Has anyone got a picture/diagram of the calliper? I can't see any Allen bolts on the calliper I'm pretty sure I've got the right bolts but just want to check.

Thanks

Normally 13mm mate and 17mm spanner to stop it spinning

Yep mine are 13mm top and bottom aswell

Thanks for the replies. The spinning is the problem that's why I thought I had it wrong. 19mm spanner too small but a 20mm too big.

Should be 17mm you may just have to grind the spanner down a bit as it's a tight fit.

It is just a tight fit with the spanner.

The 7mm Allen key is for the front callipers.

Yes - as you say - think that is where messages got crossed... 7mm for fronts...

Back to the rears... By the time the 17mm start spinning, then some water pump pliers might fit, not a lot of holding power is needed (esp if you add a smidgen of WD40 (just don't spray on disc)) worked for me...

I found the 13mm bolt utterly seized on mine and needed a squirt of plusgas to help, plus lots of wiggling the 17mm nut, which wasn't quite so locked in place. Still ended up rounding off one of the 13mm bolts during my attempts to work it loose. Thankfully new Mintex pads came with new bolts!

7mm allen key definitely only on the front calipers.

Just done my back brakes and can confirm it's 13 mm bolts and 17mm on the slider.
