Help - stuck rotor : how to remove?

[d9988]

Hello. I started working on my project which is replacing all rotors and pads. I found several Supra repair manuals which got me through the Caliper removal process on the front. I was expecting the rotor to just slide off once I got the caliper removed, but it will not. I did search around and the closest thing I could find was advice to "hit the rotor from behind with mallet," which I tried.

 

Is there a bolt or screw that I'm missing or do I just need to hit it harder to knock it lose? Any advice would be appreciated, thanks. I'm posting a pic that shows where I'm at right now. It's a 94 TT US model.

I think there should be a pair of extra "unused" bolt holes somewher on the disc hub.

screw in a pair of suitably sized bolts and this should force the disc off.

I read this somewhere on here I think.

 

Found something

Yeah.. the above explains how it was for the rear for me.

 

I've never had a problem removing the front disks - UK spec, so same as your US ones.

 

I can see the two holes in that picture though. You want to thread a screw in both of those with a ratchet as described in the above thread that John has found.

As above really, either an M6 or M8 bolt (can't remember which though). Remember to give the hub face a good wire-brushing afterwards to clean off any crap and then slap on a bit of copper grease to prevent it happening again.

OK I will try that as soon as I get ahold of the correct sized bolt - couldn't find any lying around.

 

2 more questions I should get out the way before I start workign on the brakes again:

 

1)bleeding the brakes. can someone briefly describe a good way to do this with 1 person, or post a link? I will be working on 1 corner at a time.

 

2)lube. What parts do I need to apply grease/lube to (other than the hub mentioned above)?

 

Thanks for the help guys!

1)bleeding the brakes. can someone briefly describe a good way to do this with 1 person, or post a link? I will be working on 1 corner at a time.

Get yourself one of the 1-man bleeding kits (generally a sealed tub with a hose coming out of it). Starting at the caliper farthest away from the master cylinder / reservoir (i.e. n/s/r), attach the tube to the nipple and loosen the nipple off. Press the brake pedal down 5 - 10 times then check the hose to see if there is any sign of small bublles. If there is keep pressing the pedal and checking til they've all gone. Tighten up the bleed nipple, remove the hose then move on to the next one.

 

2)lube. What parts do I need to apply grease/lube to (other than the hub mentioned above)?

 

Copper grease the backs of the pads as well. Also, make sure you thoroughly clean your new discs with a decent brake cleaner (Halfords own brand is crap imo).

 

Good luck

If you start beating on a disc to get it off expect to be changing that hub bearing pretty soon. Use heat and the 8mm threaded holes put in front and rear discs for this very purpose.

New question: all of my brake fluid has drained out of the reservoir (mostly onto the floor). All that is left is whatever is in the brake lines.

 

I will add the fluid/bleed after I get all the rotors and calipers back on. Is it okay to add Synthetic DOT3 brake fluid? A small amount will mix with what is left in the brake lines (which is regular DOT3), not sure if that's fine or not.

 

Also, for bleeding is the recommended order o/s/r n/s/r o/s/f n/s/f?

I'd go for 5.1 or something rather than Dot 3
