HYDRAULIC FLUID CONTAMINATION Contaminated hydraulic fluid U major cause of swollen cups, scored cylinders and leakage- (Use only S.A E. approved heavy duty high temperature fluid I Equal hy draulic pressure means equal brake effort. Flush system with alcohol if these con ditions exist HYDRAULIC LINES Visually Inspect lines, fittings and hoses for "dampness" This may indicate high pressure leakage Weak hoses cause "spongy" pedal. MASTER CYLINDER Hard or sinking pedal points to swollen cups, internal leakage or plugged vents WHEEL CYLINDERS Scoring, cup swelling and sludging as a result of fluid contamination can cause "lag time" between cylinders, leading to grab or pull at one or more wheels POWER UMTS Pedal loss hard pedal or lack of assist are trouble signs Consult manual or. your unit Check valves should be above carburetor intake on most units to avoid gasoline feed back. Examine all hoses for vacuum leaks BACK PLATES Inspect for bent plates and anchor pins, worn shoe pads, frozen adjustors or anchor blocks BRAKE DRUMS True up surfaces to within specified limits Excessive oversize weakens drums Brake drums should be of equal size actors axles Do not install Velvetouch Metalik on passenger car drums that are more than .060 ' oversize or truck drums more than 090' oversize. PEDAL LINKAGE Check linkage with master cylinder disconnected for binding, wear or interference BRAKE SHOES Velvetouch Metalik lining on these shoes have been accurately pre-gTound by an au thorized bonder. It Is not necessary or desirable to regnnd Specified heel and toe clearance must be observed for maximum efficiency. Observe identification and location of primary and secondary, or forward and reverse shoes, as indicated m the diagrams. BRAKE SPRINGS Tension is destroyed by heat or flexing To balance shoe return action, replace shoe return springs and hold-down springs WHEEL BEARINGS Remove, clean and inspect Re-lubncate with proper grease Adjust to specifications REAR AXLES Bent rear axles or worn axle bearings are frequent causes of high lining wear and erratic braking Repair or replace defective parts GREASE SEALS Worn or damaged seals can cause dangerous brakes Velv etouch Metalik lining is not ruined as with asbestos. Heavy concentrations of oil or grease leads to erratic braking New seals are simply good insurance FRONT END ALIGNMENT (CHASSIS A SUSPENSION) Weak or broken springs, shocks and torsion bars unbalance the braking effort Sus pension and front end alignment should be checked for a balanced, sate stop. >* **. snaesasaseeuesseeeaasssesaasf
