Brake system — basic information (Transit 2)

            0

System type: Hydraulic, dual-circuit system with diagonal or longitudinal division of circuits, with front disc and rear drum brakes. A vacuum booster is used as an amplifier, the vacuum in which is created using a vacuum pump driven by a generator. The parking brake is mechanical and acts on the rear wheels. Some models may be equipped with anti-lock braking system (ABS) and traction control system.

Front brakes



Type:
  • Cars with independent front suspension - Disc, with non-ventilated or ventilated discs, with floating calipers with two pistons.
  • Cars with dependent front suspension - Disc, with fixed calipers with two or four pistons.

Disc diameter: 254 or 270 mm, depending on the model

Disc thickness (new):
  • Cast disc - 14.3 mm
  • Ventilated disc - 24.3 mm

Minimum disc thickness:
  • Cast disc - 12.15 mm
  • Ventilated disc - 22.15 mm
  • Maximum variation in disc thickness is 0.01 mm
  • Maximum disc runout (with the disk installed) — 0.13 mm
  • The minimum thickness of the brake pad linings is 1.5 mm

Rear brakes



Type: Drum, with automatic brake force regulator.

Nominal drum diameter:

Models before 1992:
  • H-type bridge - 228.6 mm
  • G-Type Axle - 254.0 mm

Models since 1992:
  • H-type bridge - 254.0 mm
  • G-Type Axle - 280.0 mm

Maximum drum diameter - 2.0 mm larger than the nominal diameter

The minimum thickness of the drum brake lining is 1.0 mm

Tightening torques for threaded connections - Nm



ABS hydraulic modulator retaining nuts:
  • Before 1998 - 25
  • Since 1998 - 10
  • Brake caliper guide bolts - 109

Guide Pin Bolts:
  • Cars with non-ventilated brake discs - 25

Cars with ventilated brake discs:
  • Lower (shorter) guide pin -31
  • Upper (longer) guide pin - 50

Bolts securing the brake disc to the hub:
  • Independent front suspension - 50
  • Dependent front suspension - 70

Nuts securing the master cylinder to the booster:
  • Standard brake system - 15
  • Anti-lock braking system - 22
  • Fixed Caliper Fixing Bolts - 109
  • Rear brake mudguard to axle - 50

Wheel nuts:
  • Five-stud wheels - 85
  • Six-stud wheels - 168
  • Vacuum pump to the alternator -7
  • Nuts securing the vacuum booster to the bulkhead - 43
