On floating caliper type disc brakes the calipers must not be inter changed from one side to the other. When the-caliper is installed on ns proper anchor plate and spindle, the bleeder screw will point to the rear of the vehicle. If a caliper is installed on the wrong side of the vehicle, it is not possible to bleed the system properly. 11- Do not attempt to clean or restore oil or grease soaked brake lin ings. When contaminated linings are found, brake linings must be replaced in complete axle sets. DRUM BRAKES " . replacement of the retracting and hold-down springs is strongly recom mended. Overheated springs lose their pull and could cause the new lining to ear prematurely, if they are not re placed. If the brake drums are heat spotted, indicating a overheated con. dition, they should be replaced. 5- if the vehicle has 30,000 or more miles of operation on the brake lin ings or signs of overheating arc pres ent when relining brakes, the wheel cylinders should be disassembled and inspected for wear and entrance of dirt into the cylinder. The cylinder cups should be replaced, thus avoiding future problems. 6. Inspect all other brake parts and replace any that arc Worn or dam aged. 7- Inspect the brake drum and, if nect$sary. refinish. Refer to Part 12-02 for refinishing. BRAKE TUBING If a section of the brake tubing be comes damaged, the entire section should be replaced with tubing of the same type. size, shape and length. Copper tubing should not be used in a hydraulic system. When bending brake tubing to fit underbody or rear axle contours, be careful not to kink or crack the tube. All brake tubing should be double flared properly to provide good leak proof connections. Clean the brake tubing by flushing with clean brake fluid before installation. . . When connecting a tube to a hose tube connector, or brake cylinder; tighten the tube fitting nut to speci fied torque with Milbar Tool 1112 144 or equivalent. brake hose . 1- Remove the wheel from the BRAKE BOOSTER ' drum, and remove the drum as outr * f lined in P in 13-02.

Prior to replacement of lining. the drum diameter should be checked to determine if oversize linings must be installed. 4- Check the condition of brake shoes, retracting springs, hold-down springs, and drum lor signs of ov erheating. If the shoes have a slight blue coloring, indicating overheating. Steel tubing is used throughout the brake system with the excepti on of the flexible hoses at the front wheels and at the rear axle housing brake tube connection. Always bleed the applicable pri mary or secondary brake system after primary or secondary brake system hose or line replacement. Centralize the pressure differential valve after bleeding the system. A flexible brake hose should be re placed if it shows signs of softening, cracking, o t other d a m a g e . When installing a new front brake hose, position the hose to avoid con tact with other chassis parts. Place a new copper gasket over the hose fit ting and thread the hose assembly into the front wheel cylinder. Engage the opposite end of the hose to' the beacket on the frame. Install the hor seshoe-type retaining clip, and con nect the tube to the hose with the lube fitting nut. - A rear brake hose should be in stalled so that it does not touch the muffler outlet pipe or shock absorber. Thread the hose into the rear brake tube connector. Engage the front end of the hose to the bracket on the ftame. install the horseshoc-type re taining clip, and connect the tube to the hose with the tube fitting nut. o n f Y 7 & (^Or \ 7 c t />. 2. ~ 0 4~ O f A PRODUCED BY FORD 13-0K 29 G en ero l Hydroulic Brok Service 12-07-29 6k C i o n >11 p m in d ean isopropyl alcohol, and inspect the parts for chipping, excessive wear or damage.

Be sure the vehicle is centered on the hoist before servicing any front end components, to avoid bending or damaging the rotor splash shield on full right or left wheel turns. 6. Riding of the brake pedal (common on left-foot applications) must be avoided during vehicle operation. 7. Tbe wheel and tire must be removed '.eparately from the brake rotor, utilise drum brakes where the wheel, tire awd lrum can be removed as a oak. 8. Do not attempt tc dean or restore oil .

Remove the wheel from the drum, and remove the d>um as outlined in2 Fart 12-02. 7- Use an industrial type vacuum 0 cleaner to repiove ail dust from the backing plates and interior of the brake drums. 3. Inspect the brake shoes for excessive lining wear or shoe damage. If the lining is won within 1/32 inch of the five! heads or if the shoes are dam aged, they must be replaced. . Replace any lining that had been contam inated with oil. grease or brake fluid. Replace lining in axle sets. Prior to replacement of lining, the drum diameter should be checked tO'determme th at-th e brake d ru m ' braking surface diameter is within specification.

If lining is damaged or worn within 1/32 inch of the rivet heads on riveted lin ings or within 0.060 inch of the shoe on bonoed linings, they must replaced. Replace any lining that has been contaminated with oil, grease, or brake fluid. Replace lining in axle sets. Prior to replacement of lining, drum diameter should be checked to determine that brake drum braking Surface diameter is within specifications. If making surface diameter exceeds specifica tion, drum must be replaced. All brake tubing should be properly double flared to provide good leakproof connections. Clean brake tubing by flushing with clean brake fluid before installation.

Asbestos dust when inhaled can be injurious to health. Do not blow out dust with an air line. A vacuum cleaner equipped for this purpose, brush or rag ahould be carefully used to remove any dust. Any dust should be contained in a sealed bag for disposal. 4. Check condition of brake shoes, retracting sp r ing, holddown springs, and drum for signs of overheating. If shoes have a slight blue color ing, indicating overheating, retracting and hold down springs should be replaced. Overheated springs lose their pull and could cause new lin ing to wear prematurely, if not replaced. If brake drums are heat spotted, indicating an overheated condition, they should be replaced. 5. Refer to part 11*15, for hub nut tightening pro cedure. Brake Booster Check booster operation as noted under Power Brake Functional Test. If brake booster is damaged or inoperative, replace it with a new booster. The brake booster is serviced only as an assembly, in cluding the check valve. Brake Tubing If a section of brake tubing becomes damaged, the entire section should be replaced with tubing of the same type, size, shape and length. Copper tub ing Should not be used in a hydraulic system . When bending brake tubing to fit body contours, be careful not to kink or crack tube. Hydraulic Lines - Double wall steel tubing is used throughout the brake system with the exception of the flexible hoses at the front and rear wheels. Always bleed applicable primary or secondary brake system after primary or secondary brake system hose or line replacement. Centralize pressure differential valve after bleeding system. 3. inspect brake shoes for excessive lining wear or shoe damage. If lining is damaged or worn within 1/32 inch of the rivet heads on riveted lin ings or within 0.060 inch of the shoe on bonded linings, they must replaced. Replace any lining that has been contaminated with oil, grease, or brake fluid. Replace lining in axle sets. Prior to replacement of lining, drum diameter should be checked to determine that brake drum braking surface diameter is within specifications. If braking surface diameter exceeds specifica tion, drum must be replaced. All brake tubing should be properly double flared to provide good leakproof connections. Clean brake tubing by flushing with clean brake fluid before installation. When connecting a tube to a hose, tube connec tor, or brake cylinder, tighten the tube fitting nut tc specified torque with the D81L-600-A inch-pounc torque wrench. 8003 0483 Broke Drum 12-10-6 IfM O V A L AN D IN STA LLA TIO N rs following opply *0 vehidej equipped with either or hydroulic broke*.
