33gtst Brakes On S1

[Oki34]

Ok so my brakes turned up yesterday.

i had a look last night and the fronts should fit .

can some one confirm for me if 33 gtst rears will fit , i didnt have time to check last night.

i got the whole lot front disc , rotors and pads. Rear rotors disc and pads all for $700 wich isnt bad.

Yeah the rears will fit but you'll have to cut the lip of the backing plate for the rotors to fit.

Chuckie - those are R32 GT-R calipers.

ok so ive started doing the brake conversion and here is what ive found so far

the bolts wich hold the stagea calipers are different they need to replaced with ( HI TENSILE ) 12mm x 1.25mm x 45mm any longer and they will hit the disc.

You can use the standard brake lines but you have to remove the collet that sits inside the threaded shank of the 33 caliper. I removed this with a self tapping screw turned in a couple of times and then pulled out.

otherwise the rest of the front just bolts straight up.

The rears are a bit different.

First you need to trim the lip off of the dust shield as it hits the disc.

I did this with a pair of tin snips to cut sections out of the lip and then folded them up and cut them off with a grinder.

You could leave the dust shield folded up but i removed the lip as it looks a bit to doddgy for my liking.

once again you can use the standard brake lines on the back you just have to do the same as the front and remove the collet.

Be mindful if you do this conversion of your rims im running 17"s not shaw the offset but i have about 10mm between the caliper and the inside face of my rim.

I will post up how much of a difference they make when i get the brakes bled.

ok so ive finished the brake conversion and it does all fit.

i decided that i would remove the dust shield off of the rear as it didnt look to good this can be done with a chisel as they are only spot welded in place.

the brakes are amazing compared to standard.

The only problem is pedal feel , either there is still air in the lines or the master cylinder is just too small to cope with the extra caliper pistons.

I will re-bleed the brakes this week and see if it makes a difference , if not i will have to look at changing over the master cylinder to maybe a r33 or gtr one it will all depend on what fits.

If anybody has done this i love to hear how it went and what master cylinder you used.

I've done this setup and had no problems with pedal feel, and am still using standard master cylinder and booster.

Possible there is still air in the system, I had the same problem when I first fitted mine but I found that I had the calipers on the wrong side on the rears.

Make sure the calipers have the bleed nipples at the top of the caliper rather than the bottom as air will not bleed out.

[25stagea]

yeah all the bleed nipples are at the top.

i might have to bleed the brakes again.

I have read elsewhere that you can have problems getting the air out of an ABS unit if fluid has drained out of it. Some are bled with nipples on the unit others need a scan tool to set it up. Anyone know if / how you can bleed the ABS unit?

[BensDR30]

I completely forgot about the ABS unit when I flushed the system... I'm sure I drained it beyond the limit, but if so it bled ok with a vacuum bleeder pump.

I removed my ABS unit and all the lines in the engine to paint it. Reinstalled them and bleed all 4 corners of the car as per normal.

Had no problems
