4.5.2 If replacing ABS control assembly, first, confirm

whether the new assembly is of dry type (brake fluid is not

full of the valve body) or wet type (brake fluid is full of the

valve body). If it is of dry type, after assembly, carry out

ventilation to the ABS assembly via Chery dedicated

diagnostic instrument, if it is of wet type, it is unnecessary to

carry out ventilation.

4.5.3 No matter whether ABS control system is subject to

ventilation, brake line shall be ventilated.

4.5.4 Lift and adequately sustain the vehicle.

4.5.5 Continuously apply the brake pedal for five to six times

(each time must apply to the maximum limit), for the last time,

it must be applied to the limit.

4.5.6 Slowly open exhaust valve until brake fluid is able to

flow.

4.5.7 Close the exhaust valve until no bubble exists in the

brake fluid.

4.5.8 Perform ventilation to each wheel one by one in

accordance with sequence of rear left, right front, right back

and left front.

Caution: the above procedures are applicable for brake line

ventilation for each brake. After ventilation, when step on the

brake pedal, the driver ought to feel it is obviously hard as

prior to disassembly and assembly.

4.5.9 After ventilation, fill in brake fluid in accordance with

the liquid level mark on the brake reservoir. The brake fluid

(DOT3 or DOT4) shall conform to national standards.

Different types of brake fluids are not compatible, therefore,

before filling, pay close attention to the type of brake fluid.

4.5.10 Check whether there is leakage in the brake line to

ensure safe driving.

Chapter Two Adjustment to Suspension System and

Four-wheel Alignment

Ⅰ. Disassembly, assembly and overhaul of front axle and suspension

1. System constructional drawing

The front axle of Chery V325 car is a kind of disconnection turning and driving axle, it uses

McPherson independent suspension, whose front suspension has driving and turning dual functions.

The upper end of the suspension connects with vehicle body; lower end connects with steering

knuckle. Subframe connects with vehicle body via elastic element, which improves diving stability

and ride comfort.
