MUITIBESTOS HANDBOOK FOR BRAKE SERVICE HUCK BRAKE fLoog and Short Shoo Type) THE shove diagram bom one of the aeveral type* oi Hack brake* found on General Motora cars prior to 1934. In principle all Hack brake* are alike, although minor change* in design and length of thoea make them appear somewhat different. The Huck brake is a highly energised mechanics, ana lining recommended for it depends greatly on the weight of the car on which the brake is rued. Multibest0* TAILORED Set* supply the correct lining for each sire of Hock brake. In addition to the TAILORED Set for the 1930-32 Chevrolet a special moulded* woven TAILORED Set is available. 1933 CHEVROLET AND PONTIAC CARS The axle shaft on the 1933 modele of the above car* is pressed Into * flange which it attached to the drum and is to arranged that a wheel puller cannot be used to remove the rear wheels and drums from these cars. There ars no peep holes in the drums to examine the brake lining. Therefore proceed as follows: 1. Remove the differential cover at the rear end. A auitable container to hold the differential grease must he placed under this assembly. 2. Talce out the necessary pins to allow removal of the two loose differential gears and the spacer block in between the end* of the two axles. 3. Push the wheel and axle assembly in from the outside of the ear about 54'. This will expose two U-shaped shaft lock washers. 4. Remove the shaft lock washers. This will allow the axle assembly which in cludes the wheel and the brake drum to be pulled out, thus exposing the brake hoes and brake mechanism. 30 MULTIBESTOS HANDBOOK FOR BRAKE SERVICE Huck Broke Adjustments Minor Adjustment it 5.

Maintenance Suggestions Due to the weight distribution on 1933 Chevrolets ;m>! Pontiacs and to the fact that the cross-shaft is full floating, it is necessary to use high friction lining on the front wheels and low friction lining on the rear wheels fo get good performance without skidding the rear wheels when the brake is applied. Vu'tibestos TAILORED Set T-614D supplies the correct combination of linings to overcome this difficulty. When centralizing brakes be sure that cam carrier bracket may be readily moved with a light tap of hammer. It is often found stuck by rust or paint, which prevent* centralizing of shoes and prevents the "energizing" action. Use penetrating oil to loosen. On Buick cars with lubricating fitting on cam assembly, over-lubrication runs through mechanism and gets on the lining. An easy way of centralizing shoes is to loosen cam carrier bolt and kick foot pedal on and off hard several times. Then hold pedal on and lock cam carrier bracket. Clearance should be about .012" at all points. A clearance of less than this will inhibit the energizing action and cause hard pedal. To take up excessive lost motion in control system, disconnect rods or cables, adjust brakes to drag, refit cables to brake, and then follow through on adju.tmenta. Late model Cadillac and LaSalle cars equipped with booster brakes are adjusted according to standard procedure. Huck brakes often develop squeals and squeaks tb3t can be traced directly to faulty adjustment or genera! sloppiness and looseness of the brake mechanism. In a few cases these noises are attributable to the lining and can be cured only by replacement of the faulty material. In the majority of cases the various causes of these noiaea may be cured by the following suggestions: Coot* j] Loose shoes due to loose spring guide |i Clips or loose spring washers. Worn anchor pins and anchor pin hole*. Side play at fittings between anchor pins and shoes. General looseness, due to weak brake springs. Shoe* not centralized--toe or heel contact. Shoes bent or cocked giving edge contact when brake is firBt applied. j ; , Backing plate warped or thrown out of line by strain of frequent emergency stops. Lack of lubrication. . Knock when brakes are applied. i. Remedy Squeeze clips together and replace shoes without springing clip# or, ir case of spring washers, insert a space? washer or replace with new spring*. Replace worn anchor pins. Insert a spacer wanher to remove all aide play. Replace with new brake springs. Ccntrali/e shoes according to stand* ard procedure. Straighten or replace shoes nr, if not too severe. Band off lining at oiiginaJ contact points. Replace backing plate or, if not too badly warped, loosen nut# on backing p!ae r4 turn. Apply heavy f*bre grease sparingly to anchor pins, guide c'ips, and other bear ing points. Tighten backing plate bolt#. 31
