The Bravada is the same as an S10 Blazer, but has AWD rather than 4wd.
I have a problem that's just started with the brakes.
When you apply the brakes, it pops the master cylinder cover off. It's just 1 corner, not the whole cover. Hasn't leaked any fluid at all and it still stops, but not the way it should.
The pedal feels spongy, like it needs bled, and there's a sort of hissing sound when you push the pedal.
I'll put the cover right back on, it'll work normal for maybe 4 0r 5 stops, then it pops the cover off again.
Any ideas?
Thanks.

 

I'm gonna guess that u probably have a rubber brake line that has a soft spot in it....
