#1 Kelsey brake servo info

Post by ollieoscarsid » Sat Jul 29, 2023 10:03 am

I remember seeing a nice article on overhaul and adjustment of the Kelsey Hayes brake booster but can’t seem to find it again. Can anyone point me in the right direction please?
My 3.8 brakes are fully overhauled and has coopercraft callipers all round, but the performance is a tad disappointing. Too much travel and little bite. They’re nicely bled, just consistently disappointing, was wondering if it’s the servo set up. Thanks. Chris.

Hi
It’s in the technical information section, in 4 parts, search for “Mike Cassidy's Kelsey Hayes brake overhaul ”.
