Brakes

1973 911T cannot lock up brakes, even on a dirt road. Brakes work but not like they should. Have changed all rubber brake lines, rotors, pads and brake fluid. System has no leaks, hard pedal, does not go soft when holding. Could the master brake cylinder be the problem?

Ed Mayo,Thanks for the help on bleeding brakes, master cyl. and pedal work. I elected to farm out the caliper drilling associated with the broken bleed valve. The service people at The Sewickley Care Store, a Pittsburgh PA area Porsche Dealer did the work and very well. My 72 911 is back in operation.

I have a 1972 911S. The brake pedal does not return all the way. Is it a problem with the linkage or the master cylinder? The springs on the linkage tube appear to be not broken. How is the master cylinder accessed on a 911? Thanks for your time and help.Regards,Jim Litter

I'm reconditioning the entire brake system on my 1970 911T, and I'm stuck - literally. The pistons in the rear calipers are really stuck. Even 180 psi of compressed air won't remove them. Any tricks up your sleeve that you might share for removing them?? Thanks in advance.

I Would like to replace the short rubber tubes that connect the brake fluid reservoir to the hard plastic lines that connect down to the master cylinder, on my 71 911T. Porsche tells me the are no longer availabe, can I use a piece of neoprene tubing I am concerned that neoprene is not compatable with brake fluid. Any advise is appreciated.

My local mechanic is having trouble mounting my newly restored rear brake calipers on my 1973 911S. They are fitted with black Pagid pads. He say he can't fit the rotor between the pads. He wants to swap SC pads which doesn't make sense to me. Thanks
