Discussion Overview

The discussion revolves around issues related to the installation of rear disc brakes on an 88 Monte Carlo racecar. Participants explore problems with braking performance, specifically the lack of rear braking, and the constraints imposed by race track rules prohibiting aftermarket parts.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant reports a lack of rear braking after installing a 9-inch Ford rear end with disc brakes and using metric calipers, mentioning attempts with a Corvette master cylinder that did not resolve the issue.
  • Another participant inquires whether the issue is due to non-functioning calipers or low braking power, suggesting the use of a pressure gauge for diagnostics.
  • Concerns are raised about potential issues such as pinched brake lines or frozen caliper pistons affecting braking performance.
  • There is a suggestion that the original configuration of the car included rear drum brakes, which may impact the current setup.
  • A participant requests recommendations for a suitable master cylinder that complies with the rules against aftermarket parts, specifying the need for a production part for street vehicles.
  • One participant recommends contacting a specific supplier for master cylinders that may fit the requirements of the car.

Areas of Agreement / Disagreement

Participants generally agree on the constraints of using only production parts and the challenges posed by the braking system. However, there are differing opinions on the specific causes of the poor braking performance and the best solutions to address the issue.

Contextual Notes

Participants have not reached a consensus on the exact cause of the braking issue, and there are unresolved questions regarding the compatibility of various master cylinders with the existing brake system.

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??
 
Engineering news on Phys.org
the rules at the race track prohibit after market parts ..right?
 
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?
 
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.

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
 
I would get on the phone and call Speedy Smiths guys..they have master cylinders for 27 Ford to a corvette..am sure the ygot one for you and cheap
