Brake servo: Check
RIGHT-HAND DRIVE
37A
There is no “RENAULT” tool to check the braking as-
sistance circuit.
Use a vacuum pump, adapting the end pieces, part
number 7701349942 and 7700105874 with a pipe, part
number 8200027352 or 8200376245.
CHECK
I - PREPARATION OPERATION FOR CHECK
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (MR 411, 02A, Lifting equip-
ment).
aRemove:
-the front right-hand wheel (see 35A, Wheels and
tyres, Wheel: Removal - Refitting, page 35A-1) ,
-the front right-hand wheel arch liner (see Front
wheel arch liner: Removal - Refitting) (MR 412,
55A, Exterior protection).II - CHECKING THE SEALS
aWhen checking the brake servo seal, ensure that
there is a perfect seal between this and the master
cylinder at (A) .
If there is a leak in this area, replace the seal be-
tween the brake servo and the master cylinder (see
37A, Mechanical component controls, Master
cylinder: Removal - Refitting, page 37A-1) .
The brake servo seals must be checked when fitted
on the vehicle and when the braking circuit is opera-
tional.
