Low Pedal

• The causes for a low pedal--a pedal that goes toward the floor--could be a loose wheel bearing or faulty front suspension, a leak or the air in hydraulic system, poor quality brake fluid or low brake fluid level, weak brake hoses, an improperly adjusted manual master cylinder pushrod, an improperly adjusted power brake hydraulic pushrod or master cylinder piston seals worn or damaged causing bypassing.
  
  

Hard Pedal

• Hard pedal could be caused by grease or brake fluid on brake pads, glazed brake pads, clogged master cylinder tubes or hoses, a seized master cylinder piston, a low engine vacuum supply to power brake, a loose or leaking vacuum hose to the power brake, a defective power brake vacuum check valve or a faulty power brake.
  
  

Grabby Brakes

• If there is drastic reaction to pressure on the pedal, it might be due to incorrect or loose pads on the plate, grease or brake fluid on the pads, a loose caliper or caliper mounting bracket, a corroded master cylinder bore,a binding brake pedal linkage or a faulty power brake.
  
  

Springy or Spongy Pedal

• A soft, springy or spongy pedal is likely caused by poor quality brake fluid, weak brake hoses that expand under pressure or air in the hydraulic system.
  
  

Sideways Vehicle Pull

• The car pulling to one side may be caused by incorrect or loose pads, grease or brake fluid on the pads or a loose caliper or caliper mounting bracket. Other reasons for this pull could include a caliper piston sticking, faulty suspension parts or misalignment or mismatched pressures in the tires.
  
  

Squealing, Clicking or Scraping

• Noise upon brake application may be caused by the pads not being seated properly to the rotor or the pads being worn out. The pads may be bent or damaged or they may be the wrong pads or plates altogether. Foreign material embedded in a pad or a rough surface could cause brake noise.
  
  

Excessive Drag on Front Brake

• Excessive drag could be due to a sticking caliper piston, a swollen caliper piston seal or an improperly adjusted push rod or switch.
  
  

Vibrating Brake Pedal

• A vibrating brake pedal is probably caused by excessive variation in the rotor thickness or excessive lateral runout in the rotor. Rust contamination on the hub surface, excessive lateral runout in the front hub or worn or damaged front-wheel bearings can also cause the brake pedal to vibrate.
  
  

Decreasing Brake Pedal Travel

• If the brake pedal is not traveling enough, it could be because a master cylinder compensating port is plugged, the master cylinder cups are swollen or the push rod or switch are improperly adjusted.
  
  

Brake Drag

• If all the brakes drag even though the brake adjustment is correct, it may be a binding brake pedal, soft or swollen rubber parts caused by incorrect or contaminated brake fluid, a plugged master cylinder compensating port or an improperly adjusted push rod or switch.
  
  

Service Precautions

• Worn or damaged square suctioned rubber piston seals should be replaced immediately. Do not interfere with the splash shield, the bleeder screw or the transfer tube when you remove or install a wheel and tire assembly. Always adjust them to meet measurement specifications. Get a firm brake pedal before moving the vehicle after any brake service. Do not touch the bridge bolts that retain the two caliper housings. Don't try to adjust the proportioning or delay valves. Do not ride the brakes while operating the vehicle.
