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 .

The HDC s wi tch i s non-lat chi ng and is ins tall ed in the floor cons ole, forward of the gear s el ect or lever. Moment aril ypres s ing and releasi ng t he HDC s wit ch connects an ignit ion power feed t o t he ABS module. W it h t he fi rs t pres s and rel easeof the HDC s wit ch, t he ABS module enables operat ion of t he HDC funct ion. W hen t he HDC swi tch i s pres s ed and rel eas edagai n, the ABS modul e dis ables operat ion of t he HDC funct ion.
To prevent mis -use of, or in the event of a broken HDC s wi tch, if t he s wit ch is press ed for more t han 10 s econds nochange of s tat e occurs. A DTC i s s tored in t he ABS module memory if t he input from the HDC swi tch i s held hi gh for moret han 1 mi nut e.
HDC Activating Stoplamps
Operat ion of t he vehi cl e s toplamps during HDC is controll ed by the CJB. The ABS module monit ors t he brake s yst emhydraulic press ure and request s t he CJB, vi a t he high s peed CAN bus, t o energi ze the s t opl amps duri ng act ive braki ng.
A press ure thres hold and ti me fil ter prevents t he s topl amps from fli ckeri ng whil e HDC i s braking.

WHEEL SPEED SENSORS

Duri ng changes of target s peed, the ABS modul e li mit s vehicle decelerat ion and accelerat ion t o -0.5 met ers per s econd

To provide a s afe t rans it ion from acti ve braking t o brakes off, the ABS module i nvokes a fade out st rat egy that graduall yrel eas es t he braking effort during act ive braking. The fade out s t rat egy occurs i f any of t he fol lowi ng condit ions i s detectedduri ng act ive braki ng:
HDC i s s elected off us i ng the HDC s wit ch.Failure of a component us ed by HDC, but not crit ical t o fade out funct ion.Accelerator pedal pres s ed when t rans mis s ion i s i n neut ral .Brakes overheat .
If fade out is i nvoked becaus e of HDC de-s el ect ion or component failure, the HDC functi on is cancel led by t he ABS module.If fade out is i nvoked becaus e t he accelerator pedal i s pres s ed wit h t he t ransmis s ion i n neut ral , or because of brakeoverheat , t he HDC funct ion remains in s tandby and res umes operati on when t he accelerat or pedal is releas ed or the brakeshave cooled.
The fade out s t rategy i ncreas es t he t arget speed at a cons tant accelerati on rat e of 0.5 m/s2 (1.64 ft/s2), unti l themaximum t arget speed i s reached, or unti l no act ive braki ng is required for 0.5 second. If t he accelerat or pedal is

W hen fade out is i nvoked becaus e of component fai lure, a warning chime is sounded and the HDC informat ion i ndi cat orlamp is ext inguis hed. The HDC warning i ndicat or lamp is t hen il lumi nat ed (on low-li ne ins trument cl ust er), or a mes s ageadvi s ing of t he fault i s dis played in the mess age cent er (on hi gh-l ine i ns t rument clus ter).

To monit or for brake overheat, t he ABS modul e monit ors t he amount of braking acti vi ty and, from thi s, es ti mat es thet emperature of each brake. If the es t imat ed temperature of any brake exceeds a pres et li mit , t he ABS module i nvokes t hefade out s t rategy.
