M20F left brake squeezing after brake bleeding

[N811SS]

One day I showed up to the airplane and there was no pressure on left brake peddle.  Mechanic got rid of the bubble by bleeding the brakes and forcing hydraulic fluid up from the bottom of the felt brake caliper.  Great, I thought, I have braking action back.  However, now I can only barely push the plane back into its parking space and I can hear that left brake screeching as it rolls backwards.  Taxi and takeoff require a lot more right rudder because those left brake pads are squeezing the rotor.   Mechanic said that’s just the way it is and no adjustments are available.   Any suggestions?

Yeah that’s not right.  I also have an F and it shouldn’t rub like that.

That being said, it’s a PIA to get the hydraulic system properly bled if your mechanic isn’t familiar.  You might want to read some previous threads on here about bleeding the system.  Some angle on the airplane (nose up) apparently helps too…

Caliper might be cocked on the pins or the caliper piston is hung up in the bore..

I had a similar issue and ended up having the caliper rebuilt. It shouldn’t bind.

The brakes are easy to bleed.  The flaps not so much.  My experience at least.

You’re probably right, but eventually they connect to the same reservoir, so it might depend on where the bubbles are?

They are two separate systems attached to same reservoir.

These kind of threads are the reason I’d say it’s difficult.  Additionally, it took me 2 mechanics to get mine bled right after fixing the MC.
