Rear disc brakes on 88 monte carlo racecar problems

[cozmiccowboy]

Have a 88 monte carlo racecar, reciently installed a 9in ford with disc brakes using metric calipers, can't use aftermarket master cylinders or proportonal valve, an have a problem with no rear braking, tried a corvette master cyclinder but didnt seem to help, any ideas??

 

[Ranger Mike]

the rules at the race track prohibit after market parts ..right?

 

[cozmiccowboy]

yes we can't use aftermarket masters or proportion valves

"No braking", meaning the calipers aren't functioning, or the braking power is just very low?

Do you have (or can you borrow) a pressure gauge for the hydraulics?

 

[Ranger Mike]

aside from the obvious, pinched brake line, frozen caliper piston...you need to find a master cylinder for the weight of your car, that uses four wheel disc brakes. I think you are using single piston calipers and the corvette may have dual pistons per caliper??

This car probably came with rear drums.

 

[cozmiccowboy]

yes the car used to have drum brakes in rear and front disc , and yes the braking is very low or poor, all the calipers are single piston front calipers front and rear and are stock monte carlo, what master would you recommend that is not aftermarket or racing and must be a production part for street vechicles
