View Full Version : Heal brake master cylinders

10-30-2020, 08:06 PM
The brakes are marked ahp , I知 not able to find any information on them. The brakes are spongy and I知 thinking the master cylinders need a rebuild. I知 looking for a rebuild kit before pulling them out of the airplane. The airplane is an early Experimental Smith completed in 2004. Any thought on parts?

Spongy is more often than not air in the line, the softness comes from that air compressing under pressure. I would drain, flush and refill. Fill from the wheel up. The cylinders that I have had fail, most times would just slowly bleed down while you hold pressure on them as they bypass inside. Cheap enough to do a refill.

Google AHP Merkle. But try Stid's advice first.
