Far side front caliper / bleeding

Post by bfisher »

Gents,

Still progressing slowly on brake rebuild & while having fitted the new front lines, i can readily bleed the closest caliper. Most pains however are with the far-side caliper which would appear to get little pressure. These are HEL lines with the 'over mudguard' line running from the closest caliper.

I have reverse bleed the lines to fill the reservoir (from far caliper); i have attempted to use mityvac tool but no success; i have used tradition approach of bleeding using manual pump / release cycle with no success. I removed the line feeding the far caliper & proved i could push fluid through that direction.

My next step tomorrow night is to remove caliper & see if it is actually pushing pistons/pads as my feeling is right now its skewed to the closest piston.

Any idea's or suggestions to overcome this problem (one assumes there air in there somewhere? I am correct to assume i should get similar / equal pressures on ether side?

If you have reverse filled the whole system from that Caliper it would suggest a leak ie it's taking in air from somewhere.

Do you have the integral brakes?
If so, if my memory serves me correct (long time since I did this), one of the front calipers is bled manually, the old fashioned way, and the other by turning the ignition on and pulling the front brake lever. The system does the rest. Brake fluid does not come from the container on the handle bar, but from the valve block underneath the fuel tank.

So Taking in Air - it had to be - you had done everything else correctly
