are cross-ply 6.9516 (175-406), or radial-ply 175/801116.

 Used in the car is a two circuit hydraulic brake system.

(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!

is hand operated. The rear wheel shoes are cable operated  by  the  lever mounted on the  floor

tunnel between the front seats.
