Wheels
Wheels are of drop forged disc type. The rim size is 127-J406 (5J-16). The wheel is fastened
with five nuts. The spare wheel is in the engine compartment.
Tyres
are cross-ply 6.9516 (175-406), or radial-ply 175/801116.
Brakes
Used in the car is a two circuit hydraulic brake system.
Service brakes
(combined with emergency brake) Include front disc brakes with movable callipers and three
cylinder blocks, and rear aluminium drum brakes with cast iron liners on the working surface,
with self aligning shoes and hydraulic cylinders.
The front and rear brakes are hydraulically operated by the foot pedal through master brake
cylinder with two coaxial pistons, and a vacuum booster. The rear brake hydraulic circuit
incorporates a pressure regulator which reduces the probability of rear wheel locking at
braking; in the case of wheel locking, the pressure regulator allows the front wheels to lock
earlier which reduces the possibility of skidding. Note - switching off the engine while in
travel deactivates the brake booster pump which in turn makes braking distances
greatly longer!
Parking brake
is hand operated. The rear wheel shoes are cable operated by the lever mounted on the floor
tunnel between the front seats.
