Help !!!!Brakes & Master Cylinder

[priobe]

Hello All,

I have been dealing with some braking issues for some time now. When I originally ordered my replica I chose to not get the Ford Granada brake caliper package.
I did however receive the 3/4 Tilton Master Cylinders.

I have been researching Master Cylinders and it seems that the Wilwood and Tilton Cylinder are identically the same. Of course neither one of the manufactors will admit to that.

I am running a Wilwood Superlite 4 piston Caliper with a piston size of 1.75 each. In the rear I am using the Dynalite Wilwood 4 piston calipers which have a 1.38 piston size.


I contacted Wilwood for a sugestion on what M/C to use. They responded back by saying to use a 3/4 for front and 7/8 for rear. In order for Wilwood to reach this decision they only asked for piston caliper sizes.


I also contacted Tilton which requested pedal ratio, tire size, weight distribution, caliper piston size and quanity. After providing them with this infomation they suggested to use a 7/8 front and 1 1/8 rear.

Who do I go with ?


The problem I am experiencing with my 3/4 M/C, is when I bleed the brakes the pedals are rock solid. Pedal travel is about 1 inch. If I hit the brake pedal and hold it down the pedal does not sink. I have checked for leaks and the system is completely dry. When I pull the car out of the garage and it begins to roll back and I hit the brakes, the pedal has more travel maybe 5-6 inch. As I approach a stop sign if I pump the pedal 1 time the pedal becomes hard again but the car does not stop well.

I am very confident that the system does not have air. Here are some of the methods of bleeding that I have tried. I have bench bleed all M/C before installation. With the pedal pumping method I understand this could damage the seals in the M/C but it is the only way to get a hard pedal and it is not leaking.


1. Phonenix Hand pump which pushes fluid backward throught the system. = soft pedal

2. Pressurized system = soft pedal

3. Pedal Pump Wilwood / Tilton recommendation: lift driver side pedal pump bleed aand have 2 people release pressure from caliper first outboard , then in board. After complete repeat steps on passenger side. = This I receive a hard pedal , rock solid but vehicle does not stop.

If you are running the Wilwood caliper setup please post what M/C you are using. I really dont want to buy a Wilwood caliper setup then a Tilton caliper setup.

Sorry for the long post
