Rear brake disc and pad removal

Guys

 

Activity for the comming weekend is the changing of my rear discs and pads i was wondering if anyone had a quick guide to doing this...?

 

I've done this on most of the cars I've owned in my life so dont imagine it will pose me to many problems but was curious about any possible pit falls with the car being a J spec

 

Any hints and tip also welcome

 

Cheers

 

Pete

You need a bolt to thread through to force the disc off. I can't remember if its 8mm or 10mm. I think it's 8mm.

 

In doing so, the disc might pull the handbrake-shoes off their pins, which might damage the erm plate that the pins clip through.

 

Make sure you've got some fine long-nose pliers to get the pins back in. Nightmare. :D

 

That's on a UK spec. I presume it's the same setup on a J-spec.

Where does this bolt go?

I've never changed discs on a Supra but I'm thinking of changing my rear discs to grooved ones to match the fronts.

 

It goes through the face of the disc (not the pad-contact area, the hub-area) and pushes against the hub to force the disc off. There are two of these holes at 180 degree to each other so you can wind a bolt a bit in the top one, then the disc will be crooked (coming away at the top but not the bottom), then wind one in the bottom, etc.

take the wheel off, the brake disc will have a hole in it, rotate the disc untill you see a adjuster.

then with a screw driver it is possible to wind the adjuster off,so that brake shoes are no longer near the disc.

it will all come clear when you see the hole!

I think it's worth noting that the hole needs to be at the BOTTOM of its rotation to see the adjuster. Use a thin flat-bladed screwdriver and flick the notches downwards a bunch of times to retract the handbrake shoes. Then there is no need for that screw people weret talking about. Upon re-fitting, tighten the adjuster all the way, then loosen by 8 notches (according to the manual) unless you are not replacing the handbrakes shoes, in which case do it fewer times (otherwise the handbrake will not bite hard) - no need to mess with the handbrake itself.

 

You'll need a big f**k-off breaker bar to crack the caliper nuts off (mine's 24" - worked a treat) and a torque wrench to do them up again (77lbs/ft) with 17mm sockets, 1 shallow and 1 deep.

 

You'll probably also want a mechanics punch to drive the brake pad pins out with. Mine are stuck like a bastard, so I'm going to chop them up with a dremel, punch out the remains and replace with new ones - someone posted the part number on here at some time or other.

 

Don't forget to use copper grease, but nowhere near the disc/pad surfaces.

I'm thinking of attempting this on Saturday morning... (My Mot is booked for 12:00) I'm sure I must be mad :)

 

Any further tips anyone? I haven't seen a guide with pics yet so I'll take a few and post something up afterwards...

Nothing that isn't already posted.

 

I'm sure you can find a handy list of the swear words you'll need, somewhere on the Internet.

As you can see the discs were pretty well worn...

 

image

I undid the two smaller bolts to remove the first bit of the calliper 14mm socket I think - Easy

 

image

Removing the second part of the calliper was more tricky... I needed a longer 17mm socket as the ones I had didn't leave enough room to work around the suspension - Once off it was all copper greased up so it floats nicely...

 

image

I didn't bother with the hand brake shoe adjuster and went with the 'wack it with a hammer approach' which worked a treat

 

image

Once the new disc was on I pushed back the pistons

re-assembled the calliper and fitted the pads and - Finnished :)
