15 - 8 BRAKES Fluid withdrawn in any bleeding operation should not be used again. Replenish fluid in the master cylinder after each cylinder isbled. If filler bottle J-713-C (filler and threaded adapter) is used, this constant check on the master cylinder is not necessary because of its large capacity and the fact that the quantity is easily watched. If the master cylinder is drained during the bleeding operation, air will enter the system and the bleeding will have to be done all over again at all four wheels. When bleeding operation is completed the master cylinder must be refilled. Check fluid level in master cylinder every 1000 miles. BRAKE FLUID Hydraulic brake fluid must have a high boiling point to prevent evaporation and to prevent any tendency to vapor lock, yet at the same time a good brake fluid must remain fluid at cold temperatures. There are some types of brake fluid that are composed of ethyl alcohol and castor oil; cellosolve and castor oil; alcohol, water, and glucose with some chromate added to retard corrosion; mineral oil; anti -freeze alcohols with no castor oil added. Brake fluids of the above types are all harmful because - Ethyl alcohol has a lower boiling point than HUDSON BRAKE FLUID, causing it to vaporize more rapidly and increasing the tendency to produce a vapor lock in the lines. Cellosolve has a rather severe action on rubber parts and should not be used for that reason. Water and glucose is worthless as water will corrode the metal parts of the system and glucose forms a sticky mass when exposed to air and has no lubricating qualities. Mineral oil, in even the smallest quantity, should never be used. The slightest trace of mineral oil will destroy the sealing qualities of the two rubber piston cups in two or three days. Never wash any hydraulic brake parts in gasoline as even the slightest amount of mineral oil present in gasoline will affect the rubber parts. <strong>Hudson</strong> Brake Fluid mixes with other brake fluids recommended by automobile manufacturers. However, do not mix <strong>Hudson</strong> Brake Fluid with any fluids containing glycerine, sugar, glucose, mineral oil or water. ADJUSTMENT HAND BRAKE LEVER ADJUSTMENT With the hand brake fully released, the brake cables should permit the anchor ends of the rear brake shoes to rest on the anchor pin; if not readjust as follows: Pull hand brake grip two notches from full release. There should be 1/8" clearance between the hand brake cable lever (5) and end of slot in lever guide plate (24). If not - adjust hand brake cable clevis (51) until 1/8" clearance is obtained. Pull rear brake cables (6) tight adjust clevises so that clevis pins just enter holes in toggle (35). All slack should be removed when clevis pins are in place and hand brake applied two notches. Check engagement of hand brake ratchet rod lock springs. Replace worn or broken springs. BRAKE PEDAL ADJUSTMENT The brake pedal lever (8) Figure 1 should have between 1/4" to 3/8" free play; this free play is the movement of the pedal lever (8) before the master cylinder push rod touches the master cylinder piston. This adjustment is important to assure that the master cylinder piston returns to its normal position, otherwise the brakes will drag.
BRAKES 15 - 9 To adjust; remove the pedal link clevis pin (10) and adjust the master cylinder to pedal push rod (12). Increase or decrease length of push rod (12) to obtain free play to between 1/4" to 3/8". Tighten the pedal link clevis nut - lubricate linkage and recheck pedal free-play. PEDAL PULLER To adapt the J-2795 Brake and Clutch Pedal Remover for the "A" series pedal rods it will be necessary to add a horseshoe washer 1/4" thick with a slot milled in the washer. The opening in the washer must be large enough to enter over remover adapter; for specifications see Figure 10. 8. Remove bolt holding bracket at rear of master cylinder. 9. Remove clutch operating lever held by woodruff key and lock bolt. 10. Remove master cylinder push rod. 11. Remove lock ring at brake cross shaft with snap ring pliers KMO-630. 12. Remove master cylinder and brake pedal cross shaft brace. 13. Remove clutch cross shaft support bracket and clutch cross shaft assembly. 14. Remove brake pedal lever assembly. INSTALLATION: 1. Install brake pedal lever on brake cross shaft. 2. Install clutch cross shaft and bracket assembly. 3. Install master cylinder and brake cross shaft brace. 4. Install brake cross shaft lock ring. REMOVAL: FIGURE 10 BRAKE PEDAL 1. Raise front of car and place stand jacks. 2. Remove nut and shakeproof washer holding pedal rod to brake pedal lever assembly. 3. Use puller J-2795 and remove pedal rod. 4. Disconnect clutch pull back spring. 5. Remove clevis pin and cotter key and disconnect clutch adjusting rod. 6. Disconnect brake follow up linkage. 7. Disconnect master cylinder push rod. 5. In stall master cylinder push rod, boot, clevis pin and cotter pin. 6. Install bolt at master cylinder support bracket. 7. Install clutch release lever, align with key and tighten bolt. 8. Install clutch adjusting rod, clevis pin, and cotter pin. 9. Install brake follow up rod and make necessary adjustment. 10. Hook up brake follow up, brake pull back, and clutch pull back-springs. 11. Install brake pedal arm, nut and washer. (Align a r m with pedal before tightening nut.) Adjust pedal for proper clearance. 12. Lower car and remove jacks
