Brake Fluid?

[omega36]

Hello..

Got my warning light on for brake fluid... irritating the crap out of me - what brake fluid should I use in my R32 GTR, and should it be safe to top it up with what brake fluid is currently in? Or do I need to bleed the whole system :effort:

[adam-__-]

It should be okay to just top it up with the new fluid, but always read the label. Some brake fluid's don't recommend mixing.

If you haven't bled the brakes in 12 months you really should bleed them through.

Also - brake fluid shouldn't get out of the system, so either your brake pads are very low or you have a leak somewhere.

oooh great, a leak now that would be fun.

perhaps ill bleed the system and fill it all up again.. i think it would have been quite some time since it was done. thanks for the advise guys!

I bought some Bendix Ultimate pads ($99) and Motul RBF600 fluid ($35) yesterday and fitted the pads in my garage after work. Put the wheels back on and checked it all over then realised I forgot to bleed the brakes. Took it for a drive and it doesn't even need bleeding, pedal feels great!

Now... if only I remembered to fit those backing plates to stop the low speed squeal

Did you skim the disks? And Skylines use Dot 3 brake fluid. We use PBR stuff at work

[benm]

Nope, ripped out the old and threw in the new - stops so much better with new ultimates than used ebc greens

Well why would u have to bleed the brakes if ur changing ur brake pads? u only have to bleed the brakes if you are doing a brake fluid flush(which is supposed to be done every 2 years) or if you have air in the system. Some people undo the bleeder valve when they are compressing the piston back in, this prevents putting pressure on ur master cylinder etc but other people just suck abit of fluid out of the resevoir(to stop it over flowing) and compress the pistons which pushes the fluid back up. If you are doing a flush you would suck most the fluid out of the resevoir, fill it up again and then bleed each corner(starting from the furthest away from the master cylinder) and suck the fluid through till u see a difference in color. Just keep an eye on the fluid level coz if u suck the resevoir dry u are well maggoted and is a pain in the ass. As for topping up the fluid it should say on the resevoir cap whether to use dot 3 or dot 4
