Car Problem Symptoms
The brake light on dash comes on and of f while driving.

Steering Wheel Shakes when I Brake

Steering wheel shakes when I brake, usually this is the most common question I received. On article I will try to answer this common problem, during braking when the brake pedal is depressed you will feel vibration on the steering wheel.

All Brakes Partly on after Brake Pedal is Release

After the brake pedal is release all brakes are still partly on.

One Wheel Locks up When Brake is Apply

When the brake is apply one of the wheel locks up or skid.

Squealing Noise on Brakes

Conditions when the car trouble occurs
The brakes produce squealing noise during braking.

Brake Pedal is Hard to Depress When Braking

Conditions when the car trouble occurs
An extra hard step is necessary when the driver step on the brake pedal to stop the car.

Rear Brake Dragging after Brake Pedal is Release

Conditions when the car trouble occurs
After the brake pedal is release the rear brakes is still partly engage or the brake is dragging.

Possible cause of car trouble
1. The shoe retracting spring is broken.
2. The piston cylinder is stuck.

Car problem troubleshooting
The car rear wheel is mostly use a drum type brake system, with the drum type brake system it consist of a cylinder piston that forces the brake shoe against the drum when the driver step on the brake pedal. When the brake shoe and the drum are made contact with each other, the car will stop. Now, when the brake pedal is release the brake shoe is pulled away from the drum by the use of the retracting springs so that the wheel will turn again freely when the car starts to move again.

Brake Warning Light Came On Steadily While Driving

The brake light came on steadily while driving your car. The brake warning lights is located on the dash board.

Clunk Noise from Front End When Braking

Conditions when the car trouble occurs
During braking when the brake pedal is depressed there is a clunk noise which can be heard coming from the front end.

Possible cause of clunk noise on the front end when braking
There is a loose component on the front suspension that produces the clunk noise.

Clunk noise from the front end when braking trouble diagnosis
Usually this is a case of a loose components coming from the front end, this kind of problem happens because when the car is moving and when the driver step on the brake pedal, all the weights of the car will be thrown forward into the front end. All of the weight that is thrown coming from the rear end will be absorbed by the front suspension including all of the components of the suspension.

Click Noise on the Front End When Braking

When the brake is applied click noise is heard coming from the front end.

Brake Pedal Vibrates When Braking

Conditions when the car trouble occurs
While applying the brake there is a vibration on the brake pedal.

Brake Pedal Goes Further than Normal

Conditions when the car trouble occurs
When the brake pedal was depressed, it goes further than it used to.

Possible cause of car trouble
There is not enough amount of brake fluid.
The brake lining is worn out.

Car problem troubleshooting
Since one of the possible causes of the car trouble is not enough brake fluid, the first thing to do is to check if there is enough amount of the brake fluid present in the system and to do this open the hood of your car then locate the reservoir for brake fluid, usually it is located on the top of brake master cylinder. Look closely if fluid level is below the upper lip of the reservoir cover, there is an indicator located on the reservoir as illustrated below.

Because the brake fluid is low when the brake pedal is depressed during brake application the pedal will travel farther than usual before it will stop. As the fluid is getting lower the farther the brake pedal will travel. Now, for instance the fluid level on the reservoir is enough or within th…

Front End Dives when Braking

Conditions when car trouble occurs
After the driver step on the brake pedal to stop the car the front end of the car dives.

Possible cause of car trouble
1)Problem with the front shocks
2)Problem with the front strut cartridges

Troubleshooting car problem
If the car front end dives when the brake is applies, this does not necessary mean that there is a problem on the brake system but rather a problem on the suspension particularly the front shock absorber or the front strut cartridges. Front suspension has two key components which is the shocks and the spring. These two components are separated with each other, however there are also cars in which these two key components are integrated into a single unit in this case it is called the strut. The shock portion of the strut is the strut cartridges or the damper.

Rattling Sound Coming from Brake

Conditions when the car trouble occur
There is a rattling noise coming from brake.

Car Problem Diagnostic
Rattling sound that comes from the brake is usually caused of loose parts on the affected brakes that produce the sound when it vibrates.

Front Brakes
For the front brakes there are two parts that can cause the noise those are the anti-rattle springs which secure the brake pads and keeps the pads from rattling, or the caliper mounting bolts which secure the support bracket.

Car Pulls to One Side When Braking

Car Problem
Car pulls to one side when the brake is apply.

Car Problem Diagnostic
When car pulls to one side when the brake is apply, there are three possible causes for this problem that is the front tires, front end and front brakes. To determine which of the three causes the problems check the car.

Check the front tires
Using a tire pressure gauge, measure the tire pressure of the left and right front tire. Compare if both tires have the same tire pressure. When tires have uneven tire pressure then the cause of the problem is imbalance tire pressure. When both tires are identically inflated then the problem is not the tire pressure. The next to check is the front end.

Grinding Noise when Braking

Car Problem
During braking grinding noise occurs.

Car Problem Diagnostic
Several problems occurs on the brake system and the most common of them all is grinding noise when braking. However if the brake produce grinding sound it does not always mean that there is a brake problem but rather it warns the driver the brakes suffers excessive worn on the brake linings and this is the starts of a bigger problem that may occur if the driver neglect this sounds.

Grinding noise when braking is produce by a metal that rubs against the metal, brake lining compose of metal inside in which when excessively worn the metal will expose and have a tendency to rub against the rotor disc or drums and will produce sound and can easily notice especially by the driver. Excessive worn out of brake linings happens when the car owner neglect the brake maintenance of the car, is after the hearing the grinding noise and the driver continues to neglect the brakes suffer a bigger problem such as uneven contact betwe…

Brake Pedal Goes to Floor

The brake pedal goes to floor when the brake is lightly applied.

Free car diagnostic: If brake pedal goes to floor when the brake is applied, it usually means that there is a leak on the master cylinder. Master cylinder consists of a primary and secondary pistons which operates on either the front or rear brakes. Both pistons is sealed with a component called “cup” when the brake pedal goes to floor the most likely to happen is that the primary cup that seals the primary piston is leaking brake fluid even when brake is lightly applied.

Brakes Making Grinding Noise

Symptoms of Car Problems: Brakes making grinding noise during braking.

Troubleshooting car problems: When brakes are making grinding noise while the brakes are applied, this indicates excessively worn brake linings. The brake lining was excessively worn down and nothing left but an exposed metal which rub against the disc or the drum depending on the location where the grinding noise is heard when applying the brake which resulted into a grinding noise. 

Spongy Brake Pedal When Braking

Conditions when car trouble occurs
The brake pedal feels spongy instead of solid when the driver steps on the brake pedal to stop the car.

Possible cause of car trouble
There is a presence of air inside the brake line

Troubleshooting car problem of brake pedal that feels spongy
The problem of spongy feeling on the brake pedal when the driver step on the pedal to stop the car, is usually an indication of a presence of air somewhere along the brake line.

Normally, if there is no problem on the brake system the brake pedal feels solid when the driver step on the brake this is because the brake fluid, that is inside the brake line cannot be compressed.

Brake system operates when the fluid is forced to flow through the brake line by depressing the brake pedal to make the car stop. Now if air is present inside the system the air can be compressed therefore instead of feeling the brake pedal to be solid, the driver may feel that the pedal is spongy when the driver steps on the brake pedal d…
