Proceed as outlined in "Minor Adjustment"— Page 12. 3. Adjust wheel bearings. 4. Check for any effect of dirt, grit or improper or contaminated fluid in hydraulic system that would cause damage to wheel cylinder cups. See remedies Nos. 2 and 4 under trouble "B". 5. Obstruction in the line may be caused by foreign material in the line or flattened or kinked tube. If dirt or gum is found in the line, remove the obstruction and flush the hydraulic system with Declene.

(D) Car pulls to one side.	1. Grease or fluid soaked lining. 2. Anchor pin adjustment not correct. 3. Loose wheel bearings, loose backing plate on rear axle or front axle or loose spring bolts. 4. Linings not of specified kind or primary and secondary shoes reversed.	1. Replace with new linings according to specifications. Grease or fluid soaked linings cannot be salvaged by cleaning. Correct cause of grease or fluid reaching the linings. 2. Adjust the brakes. (See "Major Adjustment".) NOTE—The anchor pin position is of great importance in the maintaining of equalized brakes. When the anchor pin is set so that the shoe is too close to the drum, the brake becomes severe due to heavy pressure at the anchor pin end of the secondary shoe. The anchor pin set too far in the opposite direction prevents full bearing of the secondary shoe and reduces the effectiveness of the brake. 3. Adjust the wheel bearing, tighten the backing plate on the rear and front axles and tighten spring bolts. 4. Various kinds of linings have different friction effect on the drums. Each wheel must have similar linings. Use only linings as specified by car manufacturer and guard against reversing primary and secondary shoes.
