Vehicle pulls to one side during braking
1. Defective, damaged or oil contaminated disc
brake pads or shoes on one side.
2. Excessive wear of brake shoe or pad
material or drum/disc on one side. Inspect and correct as necessary.
3. Loose or disconnected front suspension
components, inspect and tighten all bolts.
4. Defective drum brake or caliper assembly.
Remove the drum or caliper and inspect for a stuck piston or other damage
5. Inadequate lubrication of front brake
caliper slide rails. Remove caliper and lubricate slide rails
High Pitched noise when braking
1. Disc brake pads worn out. The noise comes
from the wear sensor rubbing against the disc (does not apply to all
vehicles) or the actual pad backing plate itself if the material is
completely worn away. Replace the pads with new ones immediately. If the
pad material has worn completely away, the brake discs should be inspected
for damage
2. Missing or damaged brake pad insulators
(disc brakes). Replace pad insulators
3. Linings contaminated with dirt or grease.
Replace pads or shoes.
4. Incorrect linings. Replace with correct
linings.
5. Or you just need to go to the parts store,
buy and apply some Disc Brake Pad Squeal Stop by Permatex.
Excessive brake pedal travel
1. Partial brake system failure. Inspect the entire system and correct as
required.
2. Insufficient fluid in the master cylinder. Check, add fluid and bleed
the system if necessary
3. Rear brakes not adjusting properly. Make a series of starts and stops
while the vehicle is in Reverse. If this does not correct the situation,
remove the drums and inspect the self-adjusters
Brake pedal feels spongy when pressed
1. Air in the hydraulic lines. Bleed the brake
system
2. Faulty flexible hoses. Inspect all system
hoses and lines. Replace parts as necessary.
3. Master cylinder mounting bolts/nuts loose.
4. Master cylinder defective
Excessive effort required to stop vehicle
1. Power brake booster not operating properly
2. Excessively worn linings or pads. Inspect
and replace if necessary
3. One or more caliper pistons or wheel
cylinders seized or sticking. Inspect and rebuild as required
4. Brake linings or pads contaminated with oil
or grease. Inspect and replace as required
5. New pads or shoes installed and not yet
seated. It will take a while for the new material to seat against the drum
(or rotor).
Pedal travels to floor with little or no resistance
1. Little or no fluid in the master cylinder
reservoir caused by leaking wheel cylinder(s), leaking caliper piston(s),
loose, damaged or disconnected brake lines. Inspect the entire system and
correct as necessary.
2. Worn master cylinder seals
Pedal pulsates during application
1. Caliper improperly installed. Remove and
inspect
2. Disc or drum defective. Remove and check
for excessive lateral and parallelism. Have the disc or drum resurfaced or
replace it with a new one.
