OVERVIEW
The parking brake is a manual ly actuat ed s ys t em t hat operat es brake s hoes located i n t he rear brake di scs . The ins idecent er of the rear brake dis c is manufact ured t o form the brake drum.
BRAKE SHOE ASSEMBLY
The brake s hoes are mount ed horizontal ly on an int egral brake dus t s hield and backplat e, and form an upper t rai li ng andlower l eading brake s hoe type s yst em. Retai ni ng pins pas s t hrough hol es in the dus t s hield and corres ponding hol es ineach brake s hoe bracket . Each pi n is secured t o t he brake s hoe wit h a ret ai ning cli p. The ret ai ning pins al low movement oft he brake s hoe toward the drum surface duri ng parking brake operat ion, but prevent si deways movement of the brake shoeaway from the dus t s hi eld.
An expander unit and manual adjust er are l ocat ed along t he hori zont al axis of t he dus t shi el d. The expander uni t isposi ti oned at the front of the dus t s hield and forms t he locati on for t he leading and t rai ling ends of t he brake s hoebracket s . The manual adjus t er i s mounted at t he rear of t he dust s hiel d and forms t he l ocati on and ful crum poi nt for theoppos it e ends of t he brake s hoe bracket s.
The manual adjus t er provides the means to adjust t he brake s hoe l ining t o drum clearance for maintenance purposes .Acces s t o t he manual adjus t er knurl ed wheel i s t hrough a formed hole in the front of the brake dis c. Adjust ment isrequired if t he brake s hoes or dis cs are renewed. A bedding-in procedure must al so be performed t o make s ure the drumbrakes operate sat is fact oril y.For addit ional informat ion, refer t o: Parking Brake Shoes Bedding-In (206-05 Parking Brake and Actuati on, GeneralProcedures).
The corres pondi ng ends of bot h t he upper and l ower brake shoe brackets are mai ntained i n contact wit h t he expander uni tand manual adjus t er by 2 ret urn springs . The return s pri ngs are l ocat ed bet ween t he ends of each upper and l ower brakes hoe and att ach to hol es formed in the brake shoe brackets . The ret urn springs pull t he brake s hoes away from t he drumwhen t he parking brake is released.
PARKING BRAKE LEVER
The parking brake lever is l ocat ed in t he floor cons ole bet ween the driver and pass enger s eats , and compri ses a toot hedquadrant , pawl and pres s-butt on rel eas e mechanis m. A si ngl e cabl e wi th a formed t hreaded rod-end connect s t he quadrantt o the equali zer unit , and is secured wit h eit her a locknut or a l ocking was her and nut.
The t hreaded rod all ows adjus tment s t o t he parking brake cable tens ion and parki ng brake lever travel t o be performed formaint enance purpos es.For addit ional informat ion, refer t o: Parking Brake Cabl e Adjus tment (206-05 Parki ng Brake and Actuat ion, GeneralProcedures).
The parking brake cable is routed from t he parking brake l ever equalizer, and al ong the chas si s t o t he rear parking brakeexpander uni t. The parki ng brake cabl e prot rudes t hrough t he brake dust s hiel d, and is formed wit h a nippl e that connectst o the expander unit . The oppos i te ends of each Left-Hand (LH) and Ri ght -Hand (RH) parking brake cabl e are formed wit h anipple that connect to the equali zer unit . The equal izer uni t makes sure t he LH and RH parki ng brake as s embl ies operat es imul taneous l y when the parking brake i s applied.
A micros wit ch is locat ed on t he base of the parki ng brake lever. The micros wit ch operates t he parking brake warni ngindicat or l amp l ocat ed in t he i ns t rument clus ter, when the parki ng brake i s appl ied.For addit ional informat ion, refer t o: Ins t rument Clus ter (413-01 Inst rument Cl us t er, Des cript ion and Operat ion).
PRINCIPLES OF OPERATION
As t he parking brake lever i s applied, t he toot hed quadrant rotat es and pul ls on the t hreaded rod and cable equali zer. Theequal izer pul ls t he 2 parki ng brake cables and operat es the 2 expander uni ts s i mult aneous ly. Movement of t he expanderunit caus es t he upper and l ower brake s hoes t o pivot agains t the manual adjus ter fulcrum, and t he brake s hoes cont actt he brake drum agai nst t he t ens i on of the 2 ret urn s pri ngs .
As t he parking brake lever quadrant rot ates , t he teet h on t he pawl engage wit h corresponding t eeth on the quadrant . Int he appl ied pos it ion, the pawl t eet h are held under spring t ensi on agai nst the quadrant teet h t o prevent the l ever fromdis engagi ng.
W i th the parki ng brake appli ed and the i gnit ion i n power mode 6 (ignit ion), t he mi cros wit ch connect s a ground to theins t rument clus ter and il lumi nat es t he parking brake warning i ndi cat or lamp.For addit ional informat ion, refer t o: Ins t rument Clus ter (413-01 Inst rument Cl us t er, Des cript ion and Operat ion).
W hen t he parking brake lever pres s-butt on is pres sed and t he l ever moved t o rel eas e t he parki ng brake, t he pawl teet hare rais ed clear from the quadrant t eet h. As the parki ng brake l ever i s lowered, t he parking brake cable cl oses t heexpander uni t and the brake s hoes are immediatel y moved away from the brake drum by the 2 ret urn s pri ngs .
