Brakes are one of the most important components of your vehicle for your safety and most of us take it for granted. There is quite a few components involved on your brake system to make it possible to stop your car.


Basically, the power brake system helps you provide braking power so that you don’t have to do all the work with your brake pedal.

The brakes themselves are applied at the wheel using hydraulic pressure. When we step on the brake pedal, we create pressure in the power booster that’s multiplied by vacuum from the engine. The resulting pressure pushes brake fluidthrough the master cylinder into tubes and hoses that run to the brake at each wheel.

When there’s a problem, it’s usually a fluid leak somewhere along the line. It could be at a fitting or a hose, or even an internal leak in the master cylinder. A leak gives the pressurized fluid somewhere to go other than to the brakes, so stopping power is hurt. Lose enough fluid and you can’t stop at all. Of course that’s extremely dangerous.

Denver CO Power BrakesIf you notice any decrease in stopping power or if your pedal seems mushy, you could have a problem. There are some preventive maintenance items for the power brake system that will help them last longer.

Obviously you’d want to make sure your brake fluid is filled to the recommended level. Low fluid in the master cylinder could indicate a leak or worn brake material. Master cylinder leaks are usually just because it’s worn out but, leaks in the brake lines and connectors can be minimized by replacing the brake fluid from time to time. Brake fluid has additives that protect against corrosion that can damage brake components.

Brake fluid also attracts moisture which can lead to rust – not a good thing for expensive anti-lock brake components. Also, significant amounts of water in the brake fluid can affect stopping power because the water has a much lower boiling point than brake fluid. In the high temperature environment of the brake system, the water can vaporize – and steam doesn’t do a very good job of providing hydraulic pressure.

If you are wondering what are some of the signs you need a brake job here is some tips for you.

  • Brake Squeal

    If you have a continuous squealing noise when you are driving along and not applying your brakes, this could be your brake warning indicator letting you know that your brake pads are worn out. You should come in to Auto & Tire Works as soon as it is convenient and have a brake system inspection.

    If you are getting a loud squealing noise when applying the brakes on every stop then you may have brake linings that are getting hard and crystalized, and are not operating effeciently. It could also indicate faulty brake hardware. In either case you should come in for a brake inspection as soon as possible.

  • Grinding Noise

    A deep grinding noise when applying the brakes or driving along indicates a serious problem in the brake and wheel area. It could be from brake linings worn out or from wheel bearing failure. This condition should receive immediate service and repair or should be parked. To continue driving this vehicle will lead to brake failure or wheel failure and the possibility of an accident.

  • Pedal Low/Going to Floor

    This concern also warrants immediate attention. There are many malfunctions that can cause this problem so a proper diagnosis from "The Brake Experts" is essential. If the brakes are not working properly then you should have the vehicle towed in for service.

  • Red Brake Light On

    Any time a red warning light comes on it requires immediate attention. Most common reason for this light to come in low brake fluid but if adding a brake fluid doesn't solve the problem definetly getting it checked it may be a big problem if it doesnt function proberly calling a towing company may be your best bet. At Auto & Tire Works we do check your brakes for free.

  • ABS Light On

    An amber warning light indicates a problem in the ABS system that requires attention as soon as it is convenient to bring the vehicle in. Generally it will not lead to brake failure like a red warning light, but does require prompt attention to avoid more costly repairs that may be needed if the service is delayed.

  • Losing Brake Fluid

    The brake hydraulic system is a closed system, which means that the brake fluid is not used up in normal service. There can be slight fluctuations in the brake fluid level because of brake lining wear, but if you have to add brake fluid more than once there is probably a leak in the system somewhere. This can lead to brake failure. So, service and repair should be done immediately.

  • Brake Fluid Flush

    Brake fluid wears out just like motor oil and other fluids do. Brake fluid has rust inhibitors and other additives in it that help protect and maintain proper brake operation. As moisture enters the brake system and heat breaks down these additives your brake efficiency decreases. We recommend flushing out your hydraulic system and installing new brake fluid at least every 2 years or 30,000 miles. We have the equipment to properly clean and flush your hydraulic system and maintain proper brake operation.
