How To Remove R32 Rotors

[Mr GTS4]

can someone outline how to remove the rotors off a R32. photo's would be good and what tools ( like size wise ).

and does anyone know where to get longer wheel studs from?

[Duncan]

Front calipers?

1/ Jack up car, put on chasis stands, take wheel off

2/ Undo the large bolts on the back of the caliper that bolt them to the hub. Either 17 or 19mm bolts, 17 I think. Don't undo the ones that hold the two halves of the caliper.

If you need to physically take the calipers off the car you will also need to undo the brake fluid line. If you are only changing the discs just pull the caliper out of the way, cable tie or support it on something other than the brake line.

To undo the brake line you really should use a "flare nut spanner" if you can get your hands on one. It is an open ended spanner with almost a complete circle, only a really small gap for the hose to fit thru.

If you can't get one use an open ended spanner and be * really* careful, the line can be really tight to open and it is easy to crush or strip the nut. You will loose all the brake fluid and need to rebleed everything if you undo the brake line

read my thread.. "changing brake calipers from non mspec to mspec" the process is essentially the same.. and it will show you what you need to remove.

sigh, no the photos aren't in there anymore.. i'll put the whole thing up on project32 when i have a spare minute..

hang on,

thread asks how to remove rotors...

-remove caliper (2 bolts on back that bolt it to hub)

(place caliper somewhere with it still connected to brake line

-pull brake rotor towards you.

That's it... rears can be hard due to drum handbrake, there are 2 bolt holes where you can screw in bolts to push the rotor off.

it will be impossible to fit *longer* rear studs without taking the hub apart, due to the drum brake assembly being in the way.

haha wish I had read it properly before typing all the extra crap then

Re the wheel studs, assuming it is to fit spacers, a better way is to use bolt on spacers which are more secure (bolted to the hub) but still give normal stud length for the wheel

lol thats the funniest start to a tread i'm read.. ok with just pulling the rotor off you don't have to put two bolts into those little holes between the studs to push it off?? just didn't know what they were for.

usually fronts will come off easily without too much force

I had to use those bolt holes for the rear, because the handbrake makes it hard (even with handbrake off...)

sweet thanks guys

Hey I know this is opening an old thread. But I'm trying to take off rotors on a R32 gtr and I'm trying to find the exact dimensions of the bolt holes. Anyone know what they are. I've tried a m10 bolt but it seems a little too big. Maybe the pitch is different? I've tried a m10 1.5 and a m10 1.25.
Ps I've taken off the caliper or put to the side and tried to hammer in certain spots to losen/pull off rotor.

Cheers for any help.

[Duncan]

hey good searching at least  sorry I don't have stock rears to check, did you try an m8 bolt if you think m10 is too large? It's a common thread size from memory rather than something unusual

When I took my original rear rotors off they were a bit rusted making it harder to get the bolt in. As per Duncan's comment it's a standard size at least with the OEM rotors.

Maybe give the hole/thread a good clean with some degreaser and a wire brush?

If you are sure the brakes are fully released get a bigger hammer and whack around the centre. If you can get a bottoming tap run it through the two holes to clean them up.

Thanks Duncan m8 is what standard gtrs rotors usually take however I Found the bolt. Had to go to a bolt specialist. Apparently these were a m10 in pitch 1.25. This is not standard though. Got them rusty rotors off finally!
