I'm just about to do the brakes on my 98 GS400 and was wondering what size the socket is needed to remove the rear rotors or is it needed...also, i just read a thread that said there is a spring that is hard to get the rotor off, what do you do to get this off easily...is there a tool or method?????.............thanks...Paul.....

 

i usually take a hammer and hit the rotor. not where the pads touch closer to the middle

 

you need after removing of pads a 17mm socket to remove caliper , then use a rubber mallet and tap all around the circumfrance.. it will just pop off .. so use a steering wheel puller and insert into the 2 small holes and that pushes the rotor off but when you go aftermarket rotors most of the time you will no longer have the holes so a little liquid wrend sprayed around the center hub area and a good rubber mallet will do the trick

 

For the GS....

Fronts are easy....rears are a bit harder.

For some reason....i read ppl using 7mmx1.0 bolt....and some other using 8mmx1.25 bolt to remove the stock (OEM) rotor.....well....none worked...I even bought 8mmx1.0 bolt......so I relied on sledgehammer.

To remove caliper....17mm. Two (2) bolts holding each caliper in place.

On my 2004 GS430 I used the two jack screw holes and if I remember right, 6mm X 1.25 screws. I sprayed some PB Blaster in the holes and around the hat section prior to 'jacking-off' the rotor. Good luck.

 

just did my pad and rotors last night. Man were the rears on there tight. I had to use the bolt method, since even a 2lb metal hammer would not knock them loose.

I dread the next time I have to change those rotors, since the aftermarket ones I bought do not have those screw holes.

 

You should have put some anti-sieze compound before installing.

Yah...i had to break out the sledge...and still that was not enuff....I had to use the stock jack and put a shim against the coilovers....and slowing put pressure from behind the rotor....then wack it hard on the opposite end of the hub...it just pop right off...no damage to coilovers.

Maybe a lack of road salts, but my rotors came off without much trouble.
