The Proper way for checking and testing for faulty Brake Hoses

If you're researching your car's brake system, most articles will tell you the same scary facts up front: By the time you discover your car has a brake problem, it's usually too late. Fortunately, the brake system is pretty simple, and it's easy to learn how to check the condition of different brake components.

Properly functioning brake hoses are important for a safe ride

You car's brakes are dependent on pressure and friction -- that's what makes the wheels come to a stop. When you step on the brake pedal, that pressure has to move quickly to the four corners of the car, carried around by fluid-filled brake hoses and brake lines. Generally, the metal brake lines get more attention; they're even available in dressed up and high-performance variations. But the simple rubber brake hoses are just as important to your car's safety.
Visual Inspection and feeling the pressure in the hose for a safe working life of a brake hose should be checked by a certified or brake professional.
The most effective way to look for faulty brake hoses is to check them when they are under extreme pressure. WHY? Imagine brake hoses as arteries in the human body. A person could live a normal life with hard and restricted arteries, but it’s when they exert that symptoms arise. The same applies to brake hoses. Brake hoses could appear “OK,” but when they are subjected to extreme pressure in an emergency, they need to be in good condition to handle this sudden stress. Most booster assisted braking systems can reach pressures of approximately 1500 psi.

Things to Look for when doing a Visual Inspection of Hose and Installation


1. Cracks in the outer skin of the hose - May need to bend hose for this test.



2. Blisters or bubbles in the hose - have someone to assist you and pump the brake pedal so you can see this better


3. Chafe marks from the hose rubbing against something or some other components



4. Wet stains where the hose is starting to leak 



5. Obvious bulging or expansion of the hose



6. Loose hose mounts or twisted brake line



What to feel for when doing your brake lines touch tests, it is best to compare the hose on your vehicle to a new hose. A hose in good condition will not…

  •  be hard and stiff
  •  be soft and weak
  •  expand under pressure

If one hose shows any sign of these conditions in comparison to the new hose, all hoses on the vehicle should be changed.

Some other symptoms which may indicate brake hose wear are:

1. Low or spongy brake pedal - may indicate old, soft and weak brake hoses which expand          under pressure

2. Pulling to one side during braking - may be caused by one of the front brake hoses being         blocked or restricted

3. Brake drag - may be caused by one or more restricted brake hoses

4. Intermittent brake problem - may be caused by a hose with an internal fracture creating a      one-way check valve effect

Don’t Take The Risk - Replace and Be Safe!

Symptoms of a Possible Bad or Failing Brake Master Cylinder

Image
Common signs of a faulty brake master cylinder include abnormal brake pedal behavior, contaminated brake fluid, and the Check Engine Light turning on. The brake master cylinder is one of the most significant and important components found on modern car braking systems. It serves as the central valve that pushes brake fluid through the brake lines so that the brake calipers can squeeze the pads against the rotors. It functions by pushing a metal rod through a cylinder to force fluid through the braking system to the wheels. One end of this rod is attached to the pedal and is actuated when the pedal is depressed. Usually a defective brake master cylinder will produce a few symptoms that alert the driver that service may be necessary. 1. Abnormalities in your brake pedal behavior One of the first symptoms commonly associated with a bad or failing brake master cylinder is abnormal brake pedal behavior. The master cylinder is the component that generates all of the pre

Spring Preventive Maintenance to Consider For Your Truck

So many truck and trailer drivers know all about the importance of winterizing their rigs. Fewer drivers, however, place the same amount of emphasis on caring for their vehicles after winter ends! Because winter driving can be particularly hard on your rig, you should strongly consider investing in spring truck and trailer maintenance. Obtaining your truck service in Calgary Alberta as spring arrives is a great way to ensure that your vehicle is ready to successfully weather the coming seasonal changes. You can keep your rig in tip-top shape by working with trusted technicians for all of your vehicular maintenance needs. It’s important to seek qualified maintenance technicians every time that your rig is in need of seasonal maintenance. The following are just some of the most common types of preventive maintenance you may seek when you hire someone to perform a PM service in Calgary, AB for the beginning of the spring season: Tire pressure check : Temperature changes cause air to

Spring Maintenance Tips for Truck and Trailer

Image
 Now that Winter is over and spring is settled.  This is the best time to say thanks to our hard-working vehicles for their great performance this winter by giving it a maintenance overhaul.  A spring checkup can help uncover winter damage but there may be some components that are more difficult to check without requiring a skilled technician to determine the problem. Batteries, Plugs & Wires: After a winter full of cold-morning starts, you must check your battery, plugs and wires. All of these components give the spark to your vehicle and they work extra hard when it’s cold. Winter wear and tear can compromise their performance up to 60 percent. Test and replace weak or old batteries, plugs and wires, especially those more than three years old. It will certainly be cheaper than a tow and replacement down the road. Tire Pressure:   Cold weather can reduce tire pressure, so make sure all tires (including spares) are properly inflated and balanced. Improper tire pressure leads t
