I am having a problem with bleeding the brakes, my car is a 1967 rolls royce silver shadow. we replaced all the lines and master cylinder, but we still can't get the fluid to the rear wheels. Any suggestions.

I am not familiar with Rolls Royce at all..but in braking systems,there is a metering valve pin that usually has to be held when bleeding brakes in order to get pressure to the rear wheels.
Usually this pin is either near/under the master cylinder or in some kind of valve device in line...
Trace where the rear lines come from and see if it has such a device.
The pin either has to be pushed in and held or pulled and held by an assistant.

Also ,did you bench bleed the master cylinder first?
Very important that you do.

Just a thought

Cool! To add with VERY limited RR work that Model Year 1967 was year ONE that all cars sold to US must have dual braking systems - most went front separate from rear.

Just a "betcha" for RR is that they just bough OTC GM combination brake valve (aka perportioning) or perhaps a Ford design where you did need to push a red rubber button to properly bleed brakes. You could do it without if the master cylinder was well bench bled as Jim said.

Still guessing but know that early FORDs with disc/drum brakes metered a tad too much pressure to front wheels first which went unrecalled I think as it only made a problem when stone cold with fast idle of a choke set up and front wheels would lock while backs were pushing a car that couldn't steer (ice and snow conditions only) with locked up fronts which was exicting but life was good then and who cared?
