Rear disc brakes on 88 monte carlo racecar problems

In summary: Speedway-Universal-7-8-7-8-Bore-Master-Cylinder,3124.htmlIn summary, the conversation is about a person who has recently installed a 9in ford with disc brakes using metric calipers on their 88 monte carlo racecar. They are unable to use aftermarket master cylinders or proportional valves due to race track rules. However, they are experiencing a problem with no rear braking. They have tried using a corvette master cylinder but it did not help. They are seeking advice on what type of master cylinder to use for their car. The recommendation is to contact Speedy Smiths, who offers a universal 7/8" bore master cylinder suitable for their car.

"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

1. What are the benefits of using rear disc brakes on a racecar?

Rear disc brakes offer improved stopping power and better heat dissipation compared to traditional drum brakes. They also provide more consistent braking performance and are less prone to brake fade during extended use.

2. What are common problems that can occur with rear disc brakes on an 88 Monte Carlo racecar?

Some common problems with rear disc brakes on this type of racecar include uneven brake pad wear, brake caliper sticking, and brake rotor warping. These issues can lead to decreased braking performance and potential safety hazards on the track.

3. How can I prevent or fix uneven brake pad wear on my racecar?

The most important step in preventing uneven brake pad wear is to ensure that the brake calipers are properly aligned and functioning correctly. Regular maintenance and inspections can help identify any potential issues before they become major problems. If uneven wear has already occurred, replacing the brake pads and having the calipers re-aligned can help correct the issue.

4. What are some signs that my racecar's rear disc brakes may need to be replaced?

Signs that your rear disc brakes may need to be replaced include squealing or grinding noises when braking, a pulsating brake pedal, and decreased stopping power. It is important to have your brakes inspected regularly to identify any potential issues and address them before they become major problems.

5. Are there any special considerations when upgrading to rear disc brakes on an 88 Monte Carlo racecar?

Yes, there are a few things to keep in mind when upgrading to rear disc brakes on this type of racecar. The brake system may need to be modified to accommodate the disc brakes, and it is important to ensure that all components are compatible with each other. Additionally, proper installation and alignment of the brake system is crucial for optimal performance and safety on the track.
