Brake System Test

Brake pedal sinks/fades when braking

  1. Set the parking brake, and start the engine, then turn off the A/C. Allow the engine to warm up to normal operating temperature (radiator fan comes on twice).
  2. Attach a 50 mm (2 in) piece of masking tape along the bottom of the steering wheel, and draw a horizontal reference mark across it.
  3. With the transmission in neutral (M/T) or P or N (A/T), press and hold the brake pedal lightly (about the same pressure needed to keep an A/T-equipped vehicle from creeping), then release the parking brake.
  4. While still holding the brake pedal, hook the end of the tape measure behind the brake pedal, then pull the tape up to the steering wheel. Note the measurement between the brake pedal and the reference mark on the steering wheel.
  5. Apply steady pressure to the brake pedal for 3 minutes.
  6. Watch the tape measure. If the measurement increases 10 mm (0.39 in) or less, the master cylinder is OK. If the measurement increases more than 10 mm (0.39 in), replace the master cylinder.

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. The upper caliper pin and the lower caliper pin are different. If these caliper 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 locations: Front caliper (see FRONT BRAKE CALIPER OVERHAUL ), rear caliper (see REAR 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 and support the vehicle (see «LIFT AND SUPPORT POINTS»(/acura/tsx/ii-2008-2014/remont/oem-general-information/#general-information-4-cyl__lift-and-support-points) ), 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»(/acura/tsx/ii-2008-2014/remont/mechanical-hydraulic/#conventional-brake-components-4-cyl) ).
  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 the brake pedal free play (see «BRAKE PEDAL AND BRAKE PEDAL POSITION SWITCH ADJUSTMENT»(/acura/tsx/ii-2008-2014/remont/mechanical-hydraulic/#conventional-brake-components-4-cyl) ).
  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, then replace all rubber parts in the brake system that were exposed to contaminated fluid. If the brake fluid is OK, replace the master cylinder (see «MASTER CYLINDER REPLACEMENT»(/acura/tsx/ii-2008-2014/remont/mechanical-hydraulic/#conventional-brake-components-4-cyl__master-cylinder-replacement) ).
  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»(/acura/tsx/ii-2008-2014/remont/anti-locktraction-control/#vsa-system-components-4-cyl__vsa-modulator-control-unit-removal-and-installation) ).
