Hey guys, i went to check my brake fluid level today as i just replaced both front/rear pads for my r33 gtst, and found that the fluid was right at the top of the reservoir, and i think i saw traces ov it being spilt!.What could cause this to happen?and how to i get it fixed?

been searching the forums, and the diy thread on changing brake pads never mentioned bleeding the brakes at the same time, which i think i was meant to do, could i have cause serious damage to my cylinder now?as i didnt take off the nipple, or the master cylinder cap when pulling back the pistons on the caliper.

Did you take off the cap on the reservoir before you took the pads out?

When you push back the pistons on the calipers it forces the fluid back up the lines hense over filling in the reservoir.

I undo the bleeder when i'm pushing the pistons back, for the reason you just encountered, and because i dont like the idea of pushing old fluid back into the system. I'd rather add new fluid to the master when i'm pumping it back up. It should be ok tho, just bleed it now, pump it up with the pedal and drive carefully until the pads bed in.

Yeah just wash the spilled fluid off the engine bay (but dont get any on the master)

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW )

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
