Conventional Brake Components: NVH Honda Pilot II

Rapid Brake Pad Wear, Vehicle Vibration (After a Long Drive), or High, Hard Brake Pedal

Note. Make sure that the caliper pins are installed correctly.

Upper caliper pin B and lower caliper pin A are different. If the pins are installed in the wrong location, it will cause vibration, uneven or rapid brake pad wear, and possibly uneven tire wear. For proper caliper pin location (see FRONT BRAKE CALIPER OVERHAUL ).

1. Drive the vehicle until the brakes drag or until the pedal is high and hard. This can take 20 or more brake pedal applications during an extended test-drive.
2. With the engine running, raise the vehicle on a lift, and spin all four wheels by hand. Is there brake drag at any of the wheels? YES - Go to step 3 . NO - Look for other causes of pad wear, high pedal, or vehicle vibration.
3. Turn the ignition switch to LOCK (0), press the brake pedal several times to deplete the vacuum in the brake booster, and then spin the wheels again to check for brake drag. Is there brake drag at any of the wheels? YES -Go to step 4 . NO - Replace the brake booster (see «BRAKE BOOSTER REPLACEMENT»(ref-333576-S00942525712009072100000) ).
4. Without removing the brake lines, unbolt and separate the master cylinder from the brake booster, then spin the wheels to check for brake drag. Is there brake drag at any of the wheels? YES - Go to step 5 . NO - Check the brake pedal position switch adjustment, and pedal free play (see «BRAKE PEDAL AND BRAKE PEDAL POSITION SWITCH ADJUSTMENT»(ref-333576-S40336238712009072100000) ).
5. Loosen the hydraulic lines at the master cylinder, then spin the wheels to check for brake drag. Is there brake drag at any of the wheels? YES - Go to step 6 . NO - Check the master cylinder reservoir for contamination in the brake fluid. If you find contamination, flush the entire brake system of all contaminated fluid. If the brake fluid is OK, replace the master cylinder (see «MASTER CYLINDER REPLACEMENT»(ref-333576-S23484276092009072100000) ).
6. Loosen the bleed screws at each caliper, then spin the wheels to check for brake drag. Is there brake drag at any of the wheels? YES -Check the master cylinder reservoir for contamination in the brake fluid. If you find contamination, flush the entire brake system of all contaminated fluid, then replace all rubber parts in the brake system that were exposed to contaminated fluid. If the brake fluid is OK, disassemble and repair the caliper on the wheel(s) with brake drag. NO -Look for and replace any damaged brake lines. If all brake lines are OK, replace the VSA modulator-control unit (see «VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION»(ref-333577-S39433294232009072100000) ).

Scheme 62

1. Turn the brake pedal position switch (A) counterclockwise, and pull it back until it is no longer touching the brake pedal.
2. Remove the footrest (see step 3 on «CARPET REPLACEMENT»(ref-333585-S36548707792009072100000) ).
3. Remove the driver's side kick panel (see «TRIM REMOVAL/INSTALLATION - DOOR AREAS»(ref-333585-S19189801972009072100000) ).
4. Remove the driver's center console trim (see «CENTER CONSOLE REAR TRIM REMOVAL/INSTALLATION»(ref-333586-S35065549622009072100000) ).
5. Pull back the carpet and find the cutout (B) in the insulator. Measure the pedal height (C) at the center of the pedal pad (D) to the floor without the insulator. Standard pedal height (with carpet removed): 171 mm (6.7 in)
6. Loosen the pushrod locknut (A), and screw the pushrod (B) in or out with pliers until the standard pedal height from the floor is reached. After adjustment, tighten the locknut firmly. Do not adjust the pedal height with the pushrod pressed. Brake Pedal Position Switch Clearance
7. Lift up on the brake pedal by hand. Push in the brake pedal position switch until its plunger is fully pressed (threaded end (A) touching the pad (B) on the pedal arm). Turn the switch 45° clockwise to lock it. The gap between the brake pedal position switch and the pad is automatically adjusted to 0.7 mm (0.028 in.) by locking the switch. Make sure the brake lights go off when the pedal is released.
8. Install all removed parts in the reverse order of removal.
9. Check the brake pedal free play.

Scheme 63

1. With the ignition switch in LOCK (0), inspect the play (A) at the brake pedal pad (B) by pushing the brake pedal by hand. If the brake pedal free play is out of specification, adjust the brake pedal position switch (C). If the brake pedal free play is insufficient, it may result in brake drag. Free play: 1 -5 mm (0.04-0.20 in)

Scheme 64

1. Press the parking brake pedal (A) with 294 N (30 kgf, 66 lbf) of force to fully apply the parking brake. The parking brake pedal should be locked within the specified number of clicks. Pedal locked clicks: 8 to 10
2. Adjust the parking brake if the pedal clicks are not within the specification. NOTE: Minor parking brake pedal adjustments (1 to 2 clicks) can be made with the adjusting nut (see «MINOR ADJUSTMENT»(ref-333576-S33939423302009072100000) ). If a larger adjustment is required, follow the major adjustment procedure using the adjuster nut at the parking brake drum (see «MAJOR ADJUSTMENT (TO BE DONE WHEN REPLACING PARKING BRAKE SHOES AND AFTER LINING SURFACE BREAK-IN)»(ref-333576-S41301778332009072100000) ). After installing new parking brake shoes and/or new brake disc/drum, make sure you drive the vehicle for "break-in" (see «PARKING BRAKE SHOE LINING BREAK-IN»(ref-333576-S32200863032009072100000) ).

Scheme 65

1. Raise and support the vehicle (see «LIFT AND SUPPORT POINTS»(ref-333541-S31570824132009072100000) ).
2. Release the parking brake pedal fully.
3. Press the parking brake pedal 1 click.
4. Tighten the parking brake adjusting nut (A) until the parking brakes drag slightly when the rear wheels are turned.
5. Release the parking brake pedal fully, and check that the parking brakes do not drag when the rear wheels are turned. Readjust if necessary.
6. Make sure the parking brake pedal is within the specified number of clicks (8 to 10 clicks).

1. Raise and support the vehicle (see «LIFT AND SUPPORT POINTS»(ref-333541-S31570824132009072100000) ).
2. Release the parking brake pedal fully.
3. Loosen the parking brake adjusting nut (A).
4. Remove the rear wheels.
5. Remove the access plug (A).
6. Turn the ratchet teeth on the adjuster nut (B) with a flat-tip screwdriver (C) until the shoes lock against the parking brake drum. Then back off the adjuster 10 clicks, and install the access plug.
7. Clean the mating surfaces between the brake disc/drum and the inside of the wheel, then install the rear wheels.
8. Do the minor adjustment procedure.
