Title: Pitted Master Cylinder Repair
Post by: SDDaytona on July 09, 2025, 01:34:08 PM
I had some pits in the master cylinder of my RD400 which was causing a leak. I spread JB Weld clear epoxy in the bore and then reamed it with a 14mm reamer. So far it's working..

I should clarify, I'm referring to the rear brake master cylinder. Engine is good 👍
