    Rear brakes worked fine last ride, yesterday started noticing pedal was squishy, first pump almost to the floor, second and third started building pressure, but next time, no pressure till pumped.

    Jumped to today, went out to garage,stepped on brake and no pressure, even pumping did not deliver pressure.

    There are no leaks, reservoir is full with clean and clear fluid ( with a touch of yellow).

    Any ideas??

    Thanks!!

    Usually you just need to bleed the front wheel's right caliper lower bleed valve-it's the one between the two banjo bolts , not the one on top.

    Sounds like a bad rear master cylinder.

    I agree. Your fluid is going around the seal intead of actuating the piston.

    Sounds like a leaking pressure switch... this switch is located up front and can be broken from road debris flying up into the front opening. It's a $15 part and about 20 minutes to replace.

    This is a known issue with the Vision-your master cylinder is not the issue-bleed the right front center valve & it can't hurt to bleed the rear brake to but wasn't necessasary in my case & others. This is a linked system and as crazy as it sounds bleeding at the front center caliper will take care of the problem.

    BytN2it is correct. This was an issue on the 2008 Vision and to a very very small degree on the 2009's. I had the exact same issue on my '08 Vision. If you do a VOG search on breaks you should find at least one thread I started on this subject and I got some good advice from Kevin X on this. Ultimately he recommended replacing the line.....although I cannot remember why or his exact reasoning.
    I will do a search and post the link here.
    NOT a master cylinder issue.

    Thank you everyone! I will start with bleeding the front center, if that doesnt work, move on to the more expensive stuff.


    I appreciate the help!

    Ride safe, Roger

    I have an 08 Arlen Ness Vision with 24,000 miles. I had this issue with the rear brakes come up last spring after sitting all winter. I tried the usual bleeding of the rear including using a hand vacuum pump to pull fluid from the master all the way back throgh the caliper. I went through 3 resevoirs of fluid and never pulled an air bubble, but only got meager pedal pressure. I only put on 4000 miles last year as the rest of the summer was spent on my new BMW R1200 RT.


    This year the problem is back only worse, there is virtually no pedal pressure. I am gladto have found these suggestions from others, and will attempt bleeding the front right caliper, and if that fails will have to replace the brake line.


    Thanks to all contributors.

    What they all said I would do first......but check to see if the disk roter is bent. It has the same cause as air in the line due to pads being pushed deeper into the calipers. Best wishes and hope it is nothing but air.

    I have a similar problem with my '08 JP, I bled the rear brake twice but there seems to be air getting into the back brake system. No fluid leaks or need to add fluid - just additional air.
