OVERVIEW
Power as s is t ance for the braki ng s ys t em i s provided by a vacuum operat ed, non-act ive brake boos ter.

The uni t is ins tall ed wi th t andem diaphragms that are 203.20 mm (8.00 in) and 228.60mm (9.00 in) i n diamet er and operate as a s ingle uni t.
The unit i s located on t he driver's si de of the engine compartment , and is s ealed t o t he bulkhead wit h a gas ket ands ecured wit h 4 s t uds and locki ng nuts . The brake boost er act uati ng pus h rod i s att ached t o t he brake pedal wit h a clevispin.

VACUUM COMPONENTS
For bot h t he i6 gas oli ne and TD4 dies el engi nes , t he vacuum requi red for brake booster operati on is creat ed by a vacuumpump mount ed at the rear of t he cylinder head. The vacuum pump i s dri ven by the i ntake cams haft.
A rigi d plas ti c pipe connect s the vacuum pump t o a check valve ins t al led on the front chamber of t he brake boost er. Thepipe l engt h and rout ing is different for LHD and RHD model s.
The check valve mai ntains the vacuum neces s ary for brake boos t er operat ion and prevent s air from ent eri ng the frontchamber.
