Looking for a little help regarding brakes
« on: July 26, 2020, 12:14:25 PM »
Hello forum members

My issue lies with a non Shelby but thought I would ask the group since everyone is very helpful

I have a recently purchased 71 Torino with front disk brakes and rear drums
The issue is that I do not have brakes until the pedal is nearly to floor
I replaced rear brake cylinders
Bled the car numerous times
The master has a bleeder so I bled the master on the car
I have adjusted the rod in the booster such that as soon as the pedal moves the piston in the master is moving

Any thoughts as to why I can turn the wheel on the lift when the pedal is around 50 to 70 percent down ?

Thanks for any ideas

Scott

If you are sure all the air is out then I would suspect fluid leaking past the piston in the master cyl.

Hello Pete
Hopefully the caliper photo and engine eye candy are below - using smart phone vs laptop

Did you pin the distribution block before you bled them with the tool? If not, the pin likely shifted. Rarely can you recenter a pin that has shifted all the way one way or the other without doing it with a pick though a line hole. Then it has to be pinned before bleeding.

Just for Information, When bleeding,  I did have plenty of fluid come out at each wheel during the bleeding process

I cant tell from that photo. Does your bleeder point straight up towards the fender or to the back of the car?

Correct me if Iím wrong  but that looks to be a drum brake distribution block (drum brakes at all four wheels).  Do you have a proportioning valve installed for the rear brakes?  These pictures are for a 1969 Mustang Sorry about the pictures can never get them to come out right

Yes, a drum brake block.  There is no residual valve. ( No proportioning valves on mustangs/shelbys) The master will be a drum master as well.  Smaller bore as well.

Make sure the shoes are configured correctly primary and secondary. The front shoes will have more backing plate exposed at the top next to the slave cyls. You want to have the shoes adjusted close to maintain a tight pedal. I would seat them and then back off till the drum starts to freewheel light resistance.
