???Hi guys, I had to have the 79 versy safety checked . They found the parking brake is U/S so after much discussion it seems the new calipers are faulty. So after the next set was also a problem another set was put on that worked but noew we can get no pedal pressure. Any suggestions? Brakes have been bled but still no joy...Don

I'm hoping that James Kaster can jump in on this one. Not having the Hydro-Boost braking system, I really can't answer your question.
How are they being bled? Vacuum drawing through the system? or using pressure? (person A pushes down the brake pedal while person B opens a bleeder and then closes off after pedal is to the floor) The latter often works better than vacuum.

Hi Jeff They used both methods. I was really stupid being new here I aske who did safety checks . The office sdaid C T C did a lot of them. So I thought what is easier than a simple check. They issued me the cert. I paid , on the way home the pedal went to the floor at the Main road light!!!! They are now the ones with the problem
, I will except nothing less than a sound system... Don,, They still are confused ......

I wish I had know you were looking for a mechanic. I have a contact in the Stratford area that might have able to give a recommendation. CTC (Canadian Tire for our American readers) is not 'usually' the best place to get service done in my opinion.
I bought a set of tires and Canadian tire in the '90's. When I got home I thought one of the left hand lug nuts didn't look right. Here I found out that none on the left side had been torqued down - I could move most with my fingers!!!
My dad had an air pump or a/c belt but on a FWD Chrysler years ago when we were in a bind. A half hour driving later found it loose just sitting on one of the pulleys!!!!

belive a vacuum system is needed to correctlly bleed the system.
I tested my che*y by
1) switch engine off
2) pump brake pedal a few times to remove any pressure in the safety backup
3) press down on pedal (not too hard) and start the engine.
What happens next is the pedal should go down a bit then push back on your foot. If not check the power pump and lines for a leak.
If that was ok
1) run the engine to get pressure up
2) press pedal three times
3) press for a forth time and hold , does the pedal stay in place or go down.
If going down check for leaks on your brake system.
The odds are the power steering system has air in it due to low fluid.

When I had to replace the master cylinder on my Versailles a couple of years ago, my mechanic and I did it by using pressure only; exactly the way you describe it Jeff: "person A pushes down the brake pedal while person B opens a bleeder and then closes off after pedal is to the floor".
They have worked perfectly since. I love these 4 wheel disc brakes. They really stop the car.
