Rear brake disc and pad change

Do I need to take the calliper bracket out in the rear in order to change the brake discs and pads? If so what size are the two bolts on the bracket!
Also what size bolt can I use to screw into the disc to force it off since it's stuck on due to rust, will a 10 mm bolt do?
Thanks

changing discs?, if yes just smack it with hammer, if that dont work use bigger hammer.
old discs are scrap anyway.
yes you will need to take the caliper out of the way to remove the disc.
12mm on the lower slider bolt if it hasnt been rounded off.

Thanks for the reply. I found the word for it, it's the "torque plate". Do I need to take this torque plate off?
The bgb below doesn't say I need to but i just want to make sure.

I always take it off, 2 bolts 17mm I think from memory. gets everything out the way.

Yup they seem like 17 mm just rounded off so it would've been easier if I didn't have to take that thing off.

Don't forget your wind back tool if you haven't already got one :-)

I have always used a screw driver with a wooden block to push the piston back in other cars. Do I still need a calliper tool for this car? Thanks

The rears wind in unlike the fronts.
The how to is handy

Or you can buy a tool like this
I'm sure the thread is right hand but you should double check.

Thank you I didn't know the piston screwed in and out.
Is this right/left hand thing just suit the user? Or has got something to do with the thread on the car? Cheers

Rotors have holes tapped in them you put in a bolt and do it up, its 8mm from memory and it presses the rotors off. If you get new rotors put some never seize in this thread, it stops it going rusty.
There is a special tool for screwing in the rear rotors, it looks like a cube and fits on a 3/8" drive.

For the fronts and many other brake jobs just use a large G-Clamp to push in the pistons.

Never seen one of those before! Looks handy!

It's the thread on the car, one way winds in the other out.

Thanks guys. I bought one of those brake caliper cubes but I think the screw thing is still better as the cube slips off if the piston is stubborn. Also screwing the 8mm bolt into the disc makes it much more time efficient to remove the disc rather than hammering it to hell.

In regards to the thread I think it might be right hand as I had to turn the piston clockwise to push it back in.
