Perfect hydraulic compatibility

Needed to replace an old part on our 1927 Ford due to the old master cylinder leaking. Ordered this one and it fits our car perfectly. Turns out we replaced the old one with the exact same one! The old one lasted over 20 years so we used a lot of it.

Pros
  • Rigorous specifications - Manufactured to exacting international standards SAE
Cons
  • The list goes on.

Pedal sticks on return

I bought this, bled it on a workbench before installing it, then bled every corner of the car. I've seen the piston not fully return when pumping on the bench. More often this happened when inflating onto a vehicle. It seems to be stuck at a certain point on the reverse course. The pedal does not return to the end and the brake lights are on. Parking like this will drain the battery.

Pros
  • Sturdy construction - all rubber components are high quality EPDM compound for glycol brake fluid resistance
Cons
  • Not sure
