How to Troubleshoot Brake Problems

By Deanna Sclar from Auto Repair For Dummies, 2nd Edition
1 of 8 in Series: The Essentials of Checking and Maintaining Your Vehicle’s Brakes

To check for brake problems, you step on the pedal and press it down while paying attention to how the pedal feels under your foot and evaluating the sensation. The following steps tell you what to feel for.

Start your engine, but keep it in Park with the parking brake on. (If your vehicle doesn’t have power brakes, it’s okay to do this check with the engine off.)

  1. With the vehicle at rest, apply steady pressure to the brake pedal.
    Does it feel spongy? If so, you probably have air in your brake lines. Correcting this problem isn’t difficult; unless your brakes have ABS or other sophisticated brake systems, you can probably do the job yourself with the help of a friend.Does the pedal stay firm when you continue applying pressure, or does it seem to sink slowly to the floor? If the pedal sinks, your master cylinder may be defective, and that’s unsafe.
  2. Release the parking brake and drive around the block, stopping every now and then.
    Notice how much effort is required to bring your vehicle to a stop. With power brakes, the pedal should stop 1 to 1-1⁄2 inches from the floor. (If you don’t have power brakes, the pedal should stop more than 3 inches from the floor.)
    If your vehicle has power brakes and stopping seems to take excessive effort, you may need to have the power booster replaced.
  3. If you feel that your brakes are low, pump the brake pedal a couple of times as you drive around.
    If pumping the pedal makes the car stop when the pedal’s higher up, either a brake adjustment is in order or you need more brake fluid.
    If the level of brake fluid in the master cylinder is low, buy the proper brake fluid for your vehicle and add fluid to the “Full” line on your master cylinder. Check the fluid level in the cylinder again in a few days.

If you find that you’re not low on fluid, drive carefully to a service facility and ask them to remedy the situation. When they’ve worked their magic, the pedal shouldn’t travel down as far before your vehicle stops.

Disc brakes self-adjust and should never need adjusting. Drum brakes also have self-adjusting devices that should keep the drum brakes properly adjusted. If any of the self-adjuster components on drum brakes stick or break, the drum brakes won’t adjust as they wear out, resulting in a low pedal.

As you drive around, notice how your total brake system performs, and ask yourself these questions:

  •  Does the vehicle travel too far before coming to a stop in city traffic? If it does, either your brakes need adjusting or you need new brake linings.
  • Does the vehicle pull to one side when you brake? On vehicles with front disc brakes, a stuck caliper and brake fluid leak can cause this problem.
  • Does your brake pedal pulsate up and down when you stop in a non-emergency situation? A pulsating brake pedal usually is caused by excessive lateral run-out, which can happen because your brakes are overheating from overuse.
  • Does your steering wheel shake when you brake? If it does and you have disc brakes, your front brake discs need to be professionally machined or replaced.
  • Do your brakes squeal when you stop fairly short? The squealing is a high-pitched noise usually caused by vibration. Squealing can occur when the brake linings are worn and need replacement, the brake drum or disc needs to be machined, the front disc brake pads are loose or missing their anti-rattle clips, the hardware that attaches the brake calipers is worn, or inferior brake linings are in use.
  • Do your brakes make a grinding noise that you can feel in the pedal? If so, stop driving immediately and have your vehicle towed to a brake repair shop. Further driving could damage the brake discs or drums. Grinding brakes are caused by excessively worn brake linings; when the lining wears off, the metal part of the brake pad or brake shoe contacts the brake disc or drum and can quickly ruin the most expensive mechanical parts of the brake system.
  • Does your vehicle bounce up and down when you stop short? Your shock absorbers may need to be replaced.

Never put off brake work. If this check shows that you have a problem, take care of the situation immediately. If your brakes fail, you (and other people) may be in serious trouble. Other kinds of automotive trouble may keep your vehicle from moving, but brake trouble keeps it from stopping.

Fuel Injection Systems and Why They Need Cleaning

Fuel Injection Before & After Cleaning

About your fuel injection system and why it needs routine cleaning…

 

If the engine is the heart of your car, think of the fuel injection system as its main artery: It’s your car’s source for delivering fuel, or “pumping the blood,” to the engine. This used to be the carburetor’s job. But today, most cars use fuel injectors—making service on the injection system a required part of your vehicle’s maintenance. Here’s why:

 

  • First, gas is pumped from the tank when you start the engine
  • Next, it goes through filters, rails, and the injectors
  • The injectors pump fuel into the engine’s combustion chamber, where it mixes with air and is ignited by the spark plugs—creating combustion

The heat generated by this process is intense, and the burning fuel can leave hardened carbon deposits on pistons, valves and fuel injector nozzle heads. The result can be restricted fuel flow and the need for occasional maintenance. It’s time to consider cleaning the system if your car is:

  • Hesitating or idling roughly
  • Having trouble starting
  • Getting poor gas mileage
  • Experiencing general sluggishness

It’s not uncommon for fuel injection systems to begin to falter at the 85,000 mile mark, or after about eight years. To get the most mileage out of yours:

  • Have your first system cleaning once you hit 50,000 miles
  • Change the fuel filters a little more frequently (about every 25,000 miles)

A properly maintained fuel injection system, helps provide optimum gas mileage, reduced emissions, and improved response and performance. And the biggest bonus: It may even help your engine last longer—automotive bliss to anyone on the quest for maximum mileage.
