Problem bleeding brakes on 78 mini moke

I have just replaced the rear brake cylinders & shoes, front pads and caliper pistons on a 78 mini moke with a tandem master cylinder. The problem I now have is actually bleeding the brakes. After a couple of hours with a friend pumping the pedal we cannot get any fluid to come through. Pumping only sicks fluid up to half way of the bleeding pipe and no further.

Has anyone got any tips on bleeding moke brakes? thanks eman

There isn't anything special about them. Are you sure you're doing it right?

Open nipple, push pedal, close nipple, release pedal etc?

Cheers,

Colin.

Yep and more than likely sucking air back in around the nipple thread.

If you are bleeding the brakes from scratch after a system rebuild - say after replacing lines with copper pipes & braided hoses - I have often found that using a syringe to inject b/fluid into the caliper through the bleed nipple on all four corners helps get things going alot quicker. Leave the top to the master cylinder off and move to the next corner when you hear bubbling coming from the master cylinder. Once you've done this with all four corners top the master cylinder up to full and bleed system in the normal way as described in the haynes manual or with the gunsons eezibleed tool for better results. I wouldnt use dot5 fluid and always use brake fluid from a new container that you've broken the seal off yourself. The only problem you may encounter may be with the brake balancer on the rear subframe with older cars.

Try clamping all the brake flexi hoses at the same time, then pump and bleed the master cylinder, by loosening the brakepipe connections,, when fluid comes from all the connections, the cylinder is primed, then release one clamp at a time and bleed the related brake, this usually works for me, Fitzy

For me - One problem that did arise was that in the end there was still not much pedal this was attributed to the linings not being able to be adjusted fully as the drums were distorted and needed machining.
