Thread: Brake problems on my 48 Plymouth

Tweet

Sounds like the pushrod is too long, not letting the piston return fully. If that happens, the return passage won't be opened, causing pressure to be retained in the lines. Some kits have deeper rubbers than original, causing that problem. Is there an adjusting system on the rod? I haven't worked on old Mopar brakes in decades, but most cylinders have some sort of adjustment.

Thanks to both of you for the tips, this is my first time back on the site since new years eve. I will check the master tomorrow to make sure the return hole is free or the cups are returning far enough.

Thanks again,
Tim

Let us know how it comes out.
