1990 Brake Master Cylinder

[George D.]

I need to replace the master cylinder due to leakage between the MC assy and the brake booster. Any suggestions as to best supplier for a replacement or someone that can rebuild it? I would like to keep the car as original as possible since it has recieved a Top Flight at the nationals and been PV'd.

Thanks,

If there is any pitting in the bore just rebuilding it might not last too long or it might leak from the get go. Another option would be to have it sleeved and rebuilt. That way you retain the original master cylinder and have a new wear surface ( bore ). Here is an example of some places that provide that service: http://www.brakecylinder.com/index.htm ,

George,

I rebuilt mine on my 89 Mclellan candidate, went fine. Easy job, parts from NAPA and the screw in cap that has the date code is left intact.

Do check for corrosion but depending on the type of life the car had you probably will be fine.

If all else fails you can buy a service replacement and switch the cap to the new cylinder. You may encounter other configuration issues though.

Regards...
