Need 3rd Gen Prop Valve

[deadtrend1]

For a 89-92 Rear Disc Car. The 87 one I got in now doesnt seem to get enough pressure to the rears. Thanks

FWIW; i bought a factory rear disc valve for mine when i did the ls1 rear brake swap from the drums. i didnt notice anybit of difference in stopping from when the brakes were on there for a week with teh old prop valve.

Maybe I need to bleed them again or something. But with the rear in the air, car in gear and brake pedal mashed ..... the rear tires were still spinning some

how new are the brakes/calipers? when i did my rear swap with new calipers, pads, and rotors it took a little while for my brakes to break in and stop on a dime. the e brake works just as good. just a suggestion to drive it around a little and do some hard stops. might help?
