BEFORE YOU START, LOOK AT THE PRE-ASSEMBLED PARTS TO FAMILIARIZE YOURSELF WITH THE LOCATION OF EACH PIECE AND PART! AND BE SURE TO READ THESE INSTRUCTIONS CAREFULLY!! AS YOUR SAFETY DEPENDS ON THE PROPER INSTALLATION OF THIS BRAKE KIT!

 

TO INSURE PROPER BRAKING WITH THIS KIT, A POWER BOOSTER SHOULD BE USED! IF A POWER BOOSTER IS NOT USED, A HARDER BRAKE PEDAL WILL BE EVIDENT.

***  IMPORTANT  ***
READ THIS SECTION FOR ALL INSTALLATIONS!!

TO ENSURE PROPER BRAKING WITH THIS KIT, THE MASTER CYLINDER MUST BE DISASSEMBLED, AND THE RESIDUAL CHECK VALVE DEFEATED. THIS MUST BE DONE! OTHERWISE BRAKE LINE PRESSURE WILL CONTINUE TO BUILD UP AND EVENTUALLY LOCK UP THE FRONT BRAKES. TO DEFEAT THE RESIDUAL CHECK VALVE, (REFER TO THE SHOP MANUAL FOR LOCATION) EITHER REMOVE THE VALVE ALTOGETHER OR PUNCH A SMALL HOLE IN IT TO DEFEAT ITS PURPOSE! IT IS ALSO NECESSARY TO INSTALL A 10 # CHECK VALVE IN THE REAR LINE. See page 10 for removal procedures


Remove the stock Studebaker brake parts as per the Studebaker shop manual, be sure to remove everything down to the bare spindle.

CLEAN AND INSPECT THE STOCK STUDEBAKER SPINDLES

In the kit you will see (2) cup-like machined sleeves, these are called grease seal track adapters. The purpose of these are to 1; space the rotor out to the proper location on the spindle and 2; provide a machined surface for the grease seal to ride.

This sleeve is purposely machined .002" undersize to the thick part of the spindle, so when heated, it will expand to slide over the spindle and butt up solid against the face of the spindle. When the sleeve cools, it will shrink fit on to the spindle.


TO INSTALL THE GREASE SEAL TRACK ADAPTERS, A WELDING OR BUTANE TORCH MUST BE USED! DO NOT ATTEMPT TO INSTALL THIS PART WITHOUT HEATING IT UP!!!

 

Using a butane or welding torch, and a pair of channel lock pliers, heat up one of the grease seal track adapters, red hot, and slide it over the spindle. To make sure that the grease seal track adapter is properly seated up against the spindle flange, use a small piece of pipe and a hammer and GENTLY TAP on the face of the adapter to make sure that it butts up solid against the spindle flange. Repeat the same procedure for the other side. BE SURE TO GENTLY TAP THE ADAPTER, DO NOT BEAT IT ON!!
 

Grease Seal Track Adapter Installed

Next install the caliper-mounting bracket, these brackets will fit either side! These brackets are mounted to the inside of the spindle flange (toward the engine and to the rear of the spindle) by using the back (3) holes on the spindle flange and the upper front hole on the spindle flange.

 

To install this bracket, use (4) 3/8 x 2 ¼”  hex head bolts along with washers, lock washers and lock nuts.  BE SURE TO USE RED LOCTITE ALONG WITH THE LOCK WASHERS AND LOCK NUTS!  TORQUE ALL THESE NUTS TO 36-38 FT. LBS. Repeat the above step for the other side.

 

After you have finished mounting these brackets, be sure that the caliper will be in back of the spindle, not in front as originally installed on the Studebakers. 

Right Side Bracket and Grease Seal Adapter Installed

The Cadillac rotors use the same wheel bearing as the Studebaker Car, the Studebaker Car wheel bearing must be used, this is an A-2 and A-6 bearing, and any auto parts store will know which bearings they are. When changing the bearings be sure to change the bearing races in the rotor so they are the correct ones for the bearings. The bolt pattern on the Cadillac rotor is the same as the Studebaker Truck. Be sure to use THE CADILLAC GREASE SEAL for this rotor. Part # 8871

When installing the Rotor, it may be necessary to use 2 axle nut washers to obtain proper
Adjustment on the wheel bearings.


Now install the Cadillac rotors, after-market R-M rotors (Raybestes # 5028, Bendix 141216), the only difference is the price. These rotors are from 1977 Cadillac Fleetwood’s. And are 12” in diameter. BE SURE TO ADJUST THE WHEEL BEARINGS AS PER THE STUDEBAKER SHOP MANUAL.


Before installing the disk brake pads, you will notice that on the two stock G.M. inner pads, a small piece of metal riveted to one end. This is the early warning wear indicator, on some pads, (each manufacture is just a little different in design), this rivet may have to be drilled out and the tab to which it is attached may need to be ground down, to clear the mounting bracket. On most           
Pads, this procedure is not necessary to do. The pads are Raybestes # 
                                                  
Install the Brake Pads into the caliper bracket (if not already done) Be sure to use the brake Pad clips! Slide the caliper over the rotor, and using the 14mm bolts with the lock washer, AND RED LOCTITE mount the caliper. Torque these bolts to 55 Foot Pounds.
                                                             
When mounting the calipers be sure to use the LEFT caliper on the LEFT side, and the RIGHT caliper on the RIGHT side, BE SURE THAT THE BLEEDER SCREWS ARE ON THE TOP OF THE CALIPER. The driver’s side of the vehicle is the left side and the passenger side is the right side.


Now install the brake hose’s, We make these up using a brake hose crimper and staying with the US DOT rules, ALL hoses are tested to 3000 PSI for 15 seconds.

 

Please Note Bleeder is at the top

HOW TO REMOVE A RESIDUAL VALVE FROM A MASTER CYLINDER

[1] Master cylinders used in trailer Hydraulic surge brake couplers are available either fitted with a residual valve [check valve], or without the residual valve in place. If a trailer braking system uses drum brakes the master cylinder should be equipped with a residual valve. This check valve maintains approximately 10# to 15# of hydraulic pressure [priming pressure] on the hydraulic circuit, from the master cylinder out to the drum brake wheel cylinders. This reduces the time of brake activation, by overcoming the pressure created by the drum brake return spring.

 

[2] If , however the trailer is to be equipped with DISC Brakes the 10# to 15# pressure created by the residual valve will partially activate the disc brakes, during highway travel , causing brake overheating and failure.

 

[3] If the master cylinder is equipped with a residual valve it will be necessary to remove the residual valve to eliminate it's hydraulic effect on the disc brakes. WARNING: Puncturing the residual valve can damage components internal to the master cylinder, and should not be attempted.

 

[4] To remove the residual valve, proceed as follows. As per the drawing below, remove the rubber dust boot exposing the Snap Ring. Compress the snap ring and remove. Be aware that the return spring is under compression and upon removal of the snap ring, the piston may shoot out of the cylinder. You should use some counter acting force to retard this problem. Upon removal of the snap ring, remove the piston, and the return spring. As the return spring is removed you will find the Residual valve inserted into, and thereby affixed to the return spring. Snap the Residual valve out of the return spring, then reassemble the remaining components in the reverse order from disassembly. Note that there is a thick rubber washer in the far end of the master cylinder tube that probably did not come out when the other components were disassembled. This is the washer that the residual valve previously sealed against. It is important that this washer be left in place in the master cylinder. Because of it’s thickness it will provide proper spacing for the length of the return spring to properly operate with the new disc brake assembly.

 

 [5] Now, upon final assembly you can use the master cylinder with your disc brake system.
