Obviously the quick fix is to add more, but i would like to know if anyone has had a problem with thiers leaking, if so where did it leak from? Cause i just started mine up today and it came on without warning, no puddles under the car or nothin.
Thanks for the Help

When the pads wear, the fluid level drops naturally. Check your brake pads, and see how worn they are.

will do both, thanks guys, i don't regularly check it :ashamed face: usually at every oil change but i can't imagine that is frequent enough? or is it? lol, i'll do both when i get home, hope it is the pads to give me an excuse to replace them with ceramic lol

Joe is right, but don't fill it all the way up since it will overflow when you install new pads and push the caliper pistons back.

if the light/warning dosen't come on on the way home should i just dismiss it as a fluke? I'll check either way and add more if needed of course just woundering if it could be a bigger problem if the light dosen't come back on

You should still check the fluid level even if the light doesn't come on. That's basic maintenance that shouldn't be overlooked, and check all the other fluid levels while you're at it.

it was about half down all the other fluids are fine, filled it back up and proceeded to look for the leak, i believe i found it, all of my rims are clean, but my back left rim looks like it is gather water in it, and right after i drive said "water" is splattered about so i assume it's leaking there, that being said i haven't had time nor a garage to look into it yet i'm going to do that tonight hopefully. What am i about to jump into?

quick notes:
it's leaking
from back left wheel
what can i expect damage wise?

When my leaked it was leaking a bit out of the master cylinder and also causing my front driver side brake line to leak even though it was tightened all the way on the caliper.

i shall comader my g-pas garage and take a look then, only had a LED flash light in the dark lookin in the engine bay, i'll take a closer look, hopefully it'll be warmer lol, 20* freezein balls in the street trynna find a leak

got under the car this weekend, it is not leaking from a line, but rather a seal on the caliper, from my understanding (although quite limited) that means i shall have to replace my caliper, is this correct? i have pictures and i'll try and get them when work dies down a bit

what i am seeing is when the breaks are applied (pumped a lot) a small bubble comes up and then a greenish liquid seeps from a ribber looking seal, but i'll try to get pic on this pc here soon, on another note i had no idea brake fluid was greenish lol could this be another problem?

If im not mistaken you can buy a rebuild kit for your calipers. Check summit racing. If not most parts store do a core on calipers so you just need to return your once your install one of theirs and they'll return you some money.

_________________

Yeah you can rebuild the calipers by popping out the piston (usually by using compressed air), then remove the dust boot thing (the outside accordion one), then remove the inner seal (basically a big o ring), then check for corrosion and make sure that the piston isn't pitted, then put new seals in, slide the piston back in and good to go. It's a pretty easy job, but buying a whole new or rebuild is obviously even easier.

^lol i was thinking of upgrading don't have the $$ right now but since the leak seems to be about a cap full of fluid over about 3 weeks i may be able to buy my time, hate to gamble that much though :S , can't do brembos, but i was thinking like compg/GXP, and do my rotors + pads at the same time as well cause as we all know brake dust is ugly lol, how much is the rebuild kit you guys think? may do that for now just for 1)not to gamble on it 2)for the exp, neer done something like that before lol scured i'ma fudge it up or get air in my lines, you know somethin stupid along those lines, any one got a write up or doc ID?
Thanks

EDIT:don't have the $$ for new rims ither :S

Comp G brakes are the same as you have now. GXP brakes are Brembos.

alright thank you
UPDATE:
def need a new one, rubber seals all fubar, i could always do the rebuild (besides the fact that i don't know how haha)
but i think i'll take this operrtunity to get in a set of impala calipers and some better rotors/pads
only questions i have are:
what's the part number i search on autozone (to get a rough est b4 i go on ebay) and it brough me to something like
C432 for the caliper and 14-1134 for the heay duty bracket, are those correct? sorry i'm ignorant as to how to find the correct parts numbers, shopgmparts.com confuses me lol theres 4 different calipers and they all are a dif $$ so i wasn't sure.
thanks again for the help

Why do you want to get Impala calipers? They're the same as you have now. If anything you want 12" Impala rotors and the mounting brackets, so your GP calipers line up with the larger rotors.

This kit has the 12" rotors and caliper brackets with optional brake pads:

http://shop.zzperformance.com/store/p/2 ... e-Kit.aspx

This kit has dual piston calipers, 12" rotors, caliper brackets and brake pads:

http://shop.zzperformance.com/store/p/2 ... e-Kit.aspx

The dual piston calipers will give you more stopping power.

i though impala calipers were dual pistion, direct bolt on and 12in rotors? will look into those when i get home, thanks for the links Don

The newest gen Impala (2006 & up) has dual piston calipers but I don't think they fit the Grand Prix. Besides the f-body calipers are much better made.

The 06+ Impala dual pistons 12" are a direct bolt on to all 97-08 GP's. They are the exact same thing as the Fbodies just iron calipers instead of aluminum, so are much cheaper to buy and they have the correct brackets so you don't need them retapped like the Fbodies.
Most junkyards have the Impala ones for less than 75 bucks for the pair with brackets, (much less than what ZZP tries to bend you over for). Shoot, the yard around here sells them for 40 bucks for the pair. If you want new/reman's, Rock Auto has them for about 150ish for the pair with brackets (which includes the core fee since you don't have any Imp brakes to send in) and if you want loaded ones which included the pads and brackets, it's about 200 bucks (again which includes the core fee) so then all you would need is rotors.

But back to the matter at hand.
Rob, if you just wanted to replace the stock caliper, you don't have to get a new bracket/carrier, just the caliper.

Edit:
I just looked up all the OEM part numbers for the front calipers typed it all out then realized you said the back one is leaking, so hold on, let me go look those up.

Okay, here we go now. 05+ Driver side: 88965581 Pass side: 88965582 (04's are 18048683 and 18048684). AZ rebuilt ones are Driver side: C950 Pass Side: C951. The bracket is 14-1165 for both sides. 04's AZ Caliper numbers are Driver side: C790 Pass side C791

going to be buying everything tonight (fingers crossed), so i'm lookin at pickin up just the caliper bits mentioned above from autozone (friend works there so i'ma use his discount :] ) pick up the rotors from R1 cause i hear good things, and get some pads from hawk/ebc which ever i find a coupin for haha, anything else i'm forgetting? i've herd of brake lube to stop new pads from squealing..neccesart or can i just pump'em hard a few times? (i'm midly ghetto and poor don't judge haha jk jk)
as always thanks for the help, let me know if you guys new cable internet or home phone haha or manuel labor done

Use brake lube/grease for sure! Put it on all contact points where the pads touch the carriers/brackets (will have little metal clip things on them so lube those where the pad touches) and where the calipers touch the pad backings so the piston itself and the opposite side of the caliper. Basically anything the pad touches should be lubed except the rotor obviously haha. Also a good idea to lube up the caliper slide pins and check to make sure the boots aren't torn. I'm anal and only lube the contact points and don't go buckwild and lube the entire back of the pad because then it only collects dirt and crap on areas that aren't even contacting the pad and.... it looks ugly. I notice it all the time when washing cars at the carwash and it drives me nuts

Also, since the rears have the ebrake mechanism inside the caliper, you'll need a tool to spin the piston back in. You can't just use a C-Clamp and shove the piston back in because it will mess up the ebrakes self adjusting mechanism and generally won't even allow you to push the piston in enough to get new pads to fit. They make a metal block looking tool which you can pick up at AZ for a couple bucks which will allow you to spin the piston into the caliper.

If you want to do a really thorough job, now is the time to completely flush your brake flush.
