brake rotor SSANGYONG MUSSO 2003 Service Manual

GENERAL INFORMATION 0B-13
Weather-Strip Lubrication Apply a thin film silicone grease using a clean cloth. EACH TIME THE OIL IS CHANGED Brake System Inspection This inspection should be done when the wheels are removed for rotation. Inspect the lines and the hoses for proper hookup, binding, leaks, cracks, chafing, etc.
Inspect the disc brake pads for wear. Inspect the rotors for surface condition. Inspect other brake parts, theparking brake, etc., at the same time. Inspect the brakes more often if habit or conditions result in frequent braking. Steering, Suspension and Front Drive Axle Boot And Seal Inspection Inspect the front and rear suspension and the steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect the power steering line and the hoses for proper hookup, binding, leaks, cracks, chafing, etc. Clean and inspect the drive axle boot and seals for damage, tears or leakage. Replace
the seals if necessary. Exhaust System Inspection Inspect the complete system (including the catalytic converter if equipped). Inspect the body near the exhaustsystem. Look for broken, damaged, missing, or out-of- position parts as well as open seams, holes, loose connections, or other conditions which could cause heat buildup in the floor pan or could let exhaust fumes seep into the trunk or passenger compartment. Throttle Linkage Inspection Inspect the throttle linkage for interference or binding, damaged, or missing parts. Lubricate all linkage joints and throttle cable joints, the intermediate throttle shaft
bearing, the return spring at throttle valve assembly, and the accelerator pedal sliding face with suitable grease. Check the throttle cable for free movements. Engine Drive Belts Inspect all belts for cracks, fraying, wear and proper tension. Adjust or replace the belts as needed. Hood Latch Operation When opening the hood, note the operation of the secondary latch. It should keep the hood from opening all the way when the primary latch is released. The hood
must close firmly. AT LEAST ANNUALLY Lap and Shoulder Belts Condition and Operation Inspect the belt system including: the webbing, the
buckles, the latch plates, the retractor, the guide loops and the anchors. Movable Head Restraint Operation On vehicles with movable head restraints, the restraints must stay in the desired position. Spare Tire and Jack Storage Be alert to rattles in the rear of the vehicle. The spare tire, all the jacking equipment, and the tools must besecurely stowed at all times. Oil the jack ratchet or the screw mechanism after each use. Key Lock Service
Lubricate the key lock cylinder. Body Lubrication Service Lubricate all the body door hinges including the hood,
the fuel door, the rear compartment hinges and the latches, the glove box and the console doors, and anyfolding seat hardware. Underbody Flushing Flushing the underbody will remove any corrosive materials used for ice and snow removal and dust control.
At least every spring clean the underbody. First, loosen the sediment packed in closed areas of the vehicle. Then
flush the underbody with plain water. Engine Cooling System Inspect the coolant and freeze protection fluid. If the fluid
is dirty or rusty, drain, flush and refill the engine cooling system with new coolant. Keep the coolant at the propermixture in order to ensure proper freeze protection, corrosion protection and engine operating temperature. Inspect the hoses. Replace the cracked, swollen, or
deteriorated hoses. Tighten the clamps. Clean the outside of the radiator and the air conditioning
condenser. Wash the filler cap and the neck. Pressure test the cooling system and the cap in order to help ensure proper operation.

WHEEL ALIGNMENT 2B-5
VIBRATION DIAGNOSIS Wheel imbalance causes most highway speed vibration problems. A vibration can remain after dynamicbalancing because:
A tire is out of round.
A rim is out of round.
A tire stiffness variation exists.
Measuring tire and wheel free runout will uncover only part of the problem, All three causes, known as loadedradial runout, must be checked using method of substituting known good tire and wheel assemblies on the problem vehicle. Preliminary Checks Prior to performing any work, always road test the car and perform a careful visual inspection for:

Obvious tire and wheel runout.
Obvious drive axle runout.
Improper tire inflation.
Incorrect trim height.
Bent or damaged wheels.
Debris build-up on the tire or the wheel.
Irregular or excessive tire wear.
Improper tire bead seating on the rim,
Imperfections in the tires, including: tread deformations, separations, or bulges from impactdamage. Slight sidewall indentations are normal and
will not affect ride quality.
Tire Balancing Balance is the easiest procedure to perform and should be done first if the vibration occurs at high speeds. Do an off-vehicle, two-plane dynamic balance first to correct
any imbalance in the tire and wheel assembly. An on-vehicle finish balance will correct any brake drum,
rotor, or wheel cover imbalance, If balancing does not correct the high-speed vibration, or if the vibration occurs at low speeds, runout is the probable cause.
