after hearing squeaking from my brakes, i took it by a mechanic shop and had my rear brakes replaced. i garaged my z for the winter, and after a week, i took it out for a spin, and now i dont have any brakes, whenever you tap them, there isnt any grip. i called up my mechanic and its in the shop now, again. anyone know what the problem might be ?

 

does the pedal go to the floor? Is there fluid in the reservoir?

 

yea it goes all the way to the floor

 

Are their any leaks? Puddles in the garage, etc. Can u pump them up, or does it stay to the floor?

 

you might have to bleed the brakes.

 

there was a slight leak of oil. nah, pumping doesnt work, still goes to the floor, any known causes ?

 

check fluid level. if the pedal is goign all the way in and no brake presure... it's a littel expensive but U are gonna have to replace the Master cylinder.

Courtesy parts... 238.75$http://www.courtesyparts.com/Merchan...de=46010-00005

then again u can call my good buddy rober over@ Z1 and get 1 for 54$ that's how much I got mine for. just replaced it recently.

 

thanks bardabe, i think my dad was telling me something about the master cylinder. and geez... 237 for that. i just spent 900 for my exhaust system so im outa money. ill wait and see what my mechanic says tomorrow

 

i'd go with Z1 i got mine for 54 bucks, like I said. it's hell a cheaper and U can do it yourself. it's not hard I did mine in 1hour. with a lot of chatting with my brother.

 

I wouldn't just buy the master cylinder unless you know for sure that it's the problem. It could be the caliper piston seals or the lines. Generally, it takes two people to check this. Fill it up with fluid and pump the brakes with someone under the car. Look for leaks.

Since someone just did your rear brakes, I would suspect a problem back there. Maybe they left a bleeder loose, Or damaged a line, or screwed up and loosened the wrong bolts on the caliper.... :yikes:

found out that the master cylinder needs replacing >.<

 

well I think my clutch master cylinder along with my slave cylinder need to be replased. when I drive the ar normal it's ok. but when it rains and I have a "Spirited" drive after about 35 mins the clutch slowly dies untill there is a point where the clutch predal only travels about 4.5 - 5.5 inches. the fluid level is fine. but I have to pump the clutch a couple a times before I can get it into gear @ a stop light. what U guy's think???

:doh:

 

Yeah I had the same problem w my car. I replaced the slave cylinder first..then i ended up buying the a clutch master cylinder. Advance carries reduild kits. But for the ease and convience, I would just buy new that way everything is how it should be.
