i have a 94 cavalier gls 2.0 abs etc., i've had the brakes checked out and a lot of it replaced, disks/pads all round, front caliper, rear handbrake shoes/cable and according to the mechanic, everything else is fine..
Dispite this, i'm getting hard feedback through the brake pedal and audiable "twanging", i can't think of a better word.. Brake goes hard and twangs up and down upon braking and basically stops the brakes working properly..
As it doesn't happen all the time, i've had it to the garage on several occasions and they can't find anything wrong with it.. Basically, i can't drive it at the moment, and no one can fix it..
Any idea's before i go and trade it in for something i can trust to brake.
Thanks

Brake goes hard and twangs up and down upon braking....
From what you're saying, it sounds like an abs problem.
Try taking the abs fuse out the fuse box and see if it still does it.
Check all plug/socket connections to the abs sensors, and make sure the ends of the sensors are clean, as well as the castle turret shaped ridges on the front driveshafts and at the rear of the brake drums.
You can test each sensor with a multimeter. Details here:-

thanks for that response.
elsewhere people have mentioned warped disks, and blocked air filter messing with the servo vacuum...
will get my hands dirty tomorrow after work and let you know.

Servo vacuum comes directly from inlet manifold not air filter.
