How To Rebuild R33 Gtst Callipers?

[PRIMRK]

Just want to know if any one had done a how to vid or a step by step write up on how to rebuild callipers?

I'm needing to rebuild one set of fronts and 2 sets of rears for use on my AE86 and don't feel like parting with the extra $300 in labour when I could prob do it myself given the instructions.

Can anyone help?

Mate it's fairly simple. I rebuilt a pair of fronts for my S13. Ordered the rubbers kit online, and stuck it all in between the two freshly-painted halves. Just remember how you take it apart, and take care not to damage your o-rings or scuff/scratch your pistons.

Google "nissan skyline engine manual" some where in all the clutter is a full service manual, I think its on a UK site, its to big to email or post and I CNBF looking for it myself.

you don't need to pull the caliper apart to do new seals

you just have to get the boots off each pistons which is held on by a metal o-ring then get a screw driver pry out the pistons or compressed air to push them out

then just get the rubbers out that sit in the grooves around the pistons and replace them with the new ones and pop them back in

then put new boots and o-rings back on

a rebuild kit from nissan should have new boots for the pistons and the metal o-rings that hold them on as well as the rubber rings that sit inside the slot on the piston

the hardest part that will rage you and possibly take skin off your(my) knuckles is getting the pistons out if you don't have compressed air, if you're using a screw driver to pry them out be mindful to stick a rag or something inside an exposed cylinder near it that you could slip and ram your screw driver into and scratch the side

also if you're doing the screw driver method you have to be patient and pry from a couple of different points around the cylinder to get an even lift or they just jam and you find yourself going no where

Where did you get the rebuild kit? also where can i get the tightening torques for when i stick the 2 halves back together? i watched a few youtube vids and it seems easy enough...just keep it all clean and i should be good....

Mystery, most kits come with the little 8 or 10mm o-rings to put in the gallery joins between the two halves. So if you get a kit that has them, you should pull em apart - 100% fresh!

With regard to torqueing them up, I just tightened until it 'felt right' haha. No dramas. But if you want, check that workshop manual stated above. They'll be in there.

I got my kits off of a seller on nissansilvia.com, I'll dig him up when I get home to my PC for you.

i checked out the for mentioned file but it keeps freezing up every few pages...any one got the values cos i sure as hell aint finding em any time soon with that file

you'll need compressed air and a few quick grip clamps (to hold in the cylinder that comes out easiest).

Yeh I found a trick with these is use a bunch of mdf strips and try and keep them centred then blow the things out a lil, remove a strip, blow a lil more, repeat till on pops out then the others will also almost be out.

seales are 40mm most good brake shops will carry then,

just got some in perth off shelf $60,

good luck,

[PRIMRK]

I found a couple places down here that sell em $90 for the front pair and $70 for the rear pair, so I'm up for $230 in sealing kits...ah well all i need now is these torque specs...

You don't need compressed air just take out the pads and depress brake pedal. You can put progressively thinner bits of wood bits of wood in where the pads were if you are worried or have some one watch the pistons as you do it. . A tip: do one side at a time so if you forget how it is supposed to go together you can look at the other side.
