question Bleeding QL brakes

[Tony B]

And its a curse as well! After renewing some pipe work and the master cylinder on the QL the ***ch is refusing to bleed through. Unfortunatley the master cylinder is about six inches above the cylinders so gravity won't help. Vacum bleeding, pressure bleeding and a combination have bene tried. Any suggestions welcome. A gallon of petrol and a match have come to mind. The manual says bleed from the front first, which we've tried.

If you have renewed the master cylinder, have you checked to make sure you have the correct pushrod clearance? Piston may not be returning correctly, or there is a fault in the m/cyl.

have you tried pumping fluid through the bleed nipples to the master cylinder,ie arse about face way but i have had more luck that way on difficult vehicles

Update: Richard was right, as usual! Trouble has been traced to a brocken bracket holding the brake peadal, so the push rod was off. Now all repaired so should work as per the manual (PLEASE!!)
