My lads formula rx’s need bleeding everytime we go out on it !,it’s the rear only as soon as I’ve bled them it’s fine ,& air does come out you can see it up the tube !,but leave it a week & lever comes back to the bar again.

I’m using syringes pushing fluid from the master cylinder to the caliper,I fill the syringe & it’s usually needs two syringes to get a lever !

There dosn’t appear to be any fluid loss,or evidence of leaks !,what’s up with it ?,or am I doin summert wrong ??.

Hang on… are you just bleeding from the bottom? That’s not how it’s done with Formula, really got to follow the process or it won’t work.

No,I go from master cylinder to the caliper!, what’s the technique then ?,talk to mi!. Please…

Have you lost the little o ring seals? Mine have been bled once in 2 years

Edit…kinky no worky…
Soz….

I have Rx brakes, don’t have the issue around bleeding them but do find I get brake ‘judder’ under heavy braking. It’s almost like abs. Would that be the pads being awful?
