I haven't had a third gen in over 12 years, but I finally got an 88 Iroc Convertible. The brakes on the car seem spongy but there are no leaks (no on wood) and I checked the reservior and it looks like the right level and the gasket has popped out/down. I'm going to try and bleed them this weekend, but are the brakes inherently spongy?

 

I say get a earl ss brake line kit your hoses r prob junk. That will help alot

 

depends on what you think spongy is..

they have that standerd GM power break feel, and in itself, that feels kinda soft/diffrent..... but if you own or drive a few GM, you'll find thats normal..

the disc brake rear cars tend to have a lil more pedal travel, and that generally doesnt feel too good..

our brakes also are kinda weak, so with high speed stops, you can feel the fade in the pedal.


but if they really feel spongy, you might have some air in there... or it could be the same (now water soaked) fluid that was there in 88...

also its not a bad idea to replace your flex brake lines when you bleed them... you probly have the same lines it came stock with in 88... you can either use the stock rubber, or the braided ones.

braided brakelines do alot to help the feel at the pedal... and since we dont have ABS in these cars, theres really no down side to using them.... if you do, just be extra careful not to pull on them during installation because unlike the rubber lines, the ends can pull loose off of these.
