  Q: How do you check and test the brake booster and brake pedal for proper operation on Nissan Pathfinder?

  A: In addition to particular time intervals, you should check brakes every time you remove the wheels or suspect a defect. The symptom of a vehicle pulling to one side while depressing the brake pedal can indicate potential defects in the brake system such as squealing or dragging noises when brakes are applied, too much pedal travel, pedal pulsation and fluid leaks on the tire or wheel rim interior. Jack up the car, loosen wheel lugs and put a jack stand under it for disc brake inspection. Each caliper has two pads that can be inspected by looking at both ends of the caliper through an inspection window. If the pad lining thickness is less than specified level, replace the pads with new ones. In case, it is impossible to determine their exact thickness, remove them for further examination. Measure disc thickness also to establish if it has any service left. Also inspect all brake lines and hoses for deformations, wear out, corrosion, twisting of bends cracks and leakage before putting wheels back on. For drum brakes, make sure that parking brake is disengaged; then tap on outside of drum to break it loose. Take off brake drums and clean them up along with other components of brakes system including front and rear shoes which must have a certain amount of material remaining on them at any time during their lifespan so as not to wear down too quickly from braking forces. Look for signs of fluid leakages on all brake assembly springs as well as components while cleaning out drum interiors where deep scratches score marks may exist due hard spots crack development previously mentioned matter again instructions provided above next step repeated another wheel installed condition fine remaining install reinstall this secondarily shown controlling during forward backward movement action translating conjunction other wheels separation depress normal position one both casings pull test fails indicating that has failed Parking vehicle inclined plane transmission gear lever position shift drive engine running engage neutral gears below foot released height freeplay depressed Height could also be checked adjusted if necessary.
