Well the truck has been laid up due to other problems and it's all getting sorted out today and tomorrow, so I'll be doing the brakes again, I got one of these to make sure no air is present, looks a handy tool, anyone got any experience of them.

Master Cylinder
If my master cylinder ran dry could it still have air in despite been bled many times, new brakes, discs, calipers, pipes & bled through all cylinders callipers & load valve.
My brakes are still not 100% but I'm convinced its air or a master cylinder fault. There are no visible leaks.
Anyone near Halifax any good at pressure bleeding?

I bled the brakes in this order, no leaks in the system were detected.
I adjusted handbrake prior to bleeding and it works fine.
New pads fitted in fronts.
Rear LSV bleed nipple, took a long time to get all the air out, then n/s rear brake cylinder followed by o/s brake cylinder.
Then n/s front caliper (the new one) and then the o/s caliper.
The brakes pedal with engine off was rock hard and not sinking.
Turn engine on and brake pedal got easier to push due to servo assistance but continued to sink towards floor.
Bled whole system again, same result but this time pedal never reached the floor with engine running but still a lot of pedal travel, pumping the pedal gave less travel but the brake light on dash illuminated and the brake feel went very hard but less effective braking, another lighter press of pedal and the light went off but pedal sank.
I have brakes but just not good ones and the pedal will sink if you keep pressure on it.
No leaks and fluid level is not dropping.
Has the master cylinder had it?
If so, can Rich or any of the breakers help me out?
the master cylinder is repairable by using the master repair kit which is available here in the Philippines. The brake master cylinder is the problem why your brake failed and better replaced or repair it.
