Title: Griso front brake MC
Post by: oranges3 on April 10, 2022, 06:46:02 PM

  Can anyone tell me which hole in the front brake MC is the pressure relief hole?

Not me, for sure.

Most GRiSO questions can addressed at the GRiSO Ghetto forum.

If it were me and I had the MC apart I'd clean them all. I'd not think you could meaningfully clean or unclog it as assembled.

Please advise on what you find out.

Is the replacement front brake master cylinder for a 2007 griso a Brembo PS16?

I'd go next step better------------got a bleeder on top.

MG Cycle has the RCS also but this one will work nice-----------------------------

I've never heard of this.
Why would you want to relive hydraulic pressure that wasn't involved with an antilock braking system

The piston is not coming back to the stop. I thought it may be the lever pin length, set screw that's glued in.
I have seen and had to adjust a few. None were on a new bike.
