JAGUAR, POWER BRAKE UNITS -> DESCRIPTION
Vehicle: 1992 Jaguar XJS 5.3 V12 GAS

The hydraulic booster increases pedal force by means of hydraulic pressure. The dynamic circuit of the rear brakes is supplied from the hydraulic accumulator via a control valve in the booster.

The pressure in the booster and rear brake circuit is proportional to the pedal force. The booster is composed of an actuating piston (1), and a booster piston (2), Fig. .

The movable , mechanical connection between the control valve (3) and two pistons is made by means of a scissor-lever mechanism (4), Fig. .

The control valve (3) opens the pressureless booster chamber to the reservoir (9). Sim...

JAGUAR, HYDRAULIC BRAKE SYSTEMS -> OPERATION
Vehicle: 1992 Jaguar XJS 5.3 V12 GAS

When the brake pedal is depressed, the servo unit, which is attached to the master cylinder, transfers increased pedal pressure to the master cylinder primary piston (A), Fig. , causing this piston to move forward past the by-pass port (B), and establish a rear brake line pressure in chamber (C). Pressure from primary piston return spring (D), combined with the rear brake line pressure in chamber (C), forces the secondary piston (E) forward past the by-pass port (F) to establish front brake line pressure in chamber (G).

Brake pressure entering the caliper (H) forces the pistons (J) (fo...

JAGUAR -> DESCRIPTION
Vehicle: 1992 Jaguar XJS 5.3 V12 GAS

The anti-lock braking system eliminates wheel lock by controlling hydraulic pressure applied to the brake calipers. This system, which is assisted by the power hydraulic system, also reduces tire wear and improves vehicle stability during severe braking conditions. Modulation of hydraulic pressure is achieved by a modulator containing three solenoid actuated valves; one valve in each hydraulic line to front calipers and one in a common hydraulic ...
