Brakes on my gbody

[bad1980malibu]

I change my Malibu to manual brake bought the kit from trz. I have nine inch rear with disc brakes. Is there anything else I have to do to make it work. Thanks

What all is included in the kit?

[bad1980malibu]

The master cylinder and plate for fire wall and the linkage rod for the brake petal. The rear is a spraker racing nine inch with gm calibers the brake petal feels good. But when I drive it it don’t stop like I want

Are you still using a stock proportion valve?

Also check your lines. The rubber lines going from the steel line to the calipers can collapse inside.

I put new rubber line on front. I am still running the stock proportion valve.

Get a adjustable proportion valve, the stock valve is not set up properly for a front and rear disc manual brake setup. its probably not sending enough pressure to the rear calipers.
have you done any hard braking to see what wheels lock up first?
