A car can have up to four brake hoses, with each hose attached to a braking part. Brake hoses transfer the brake fluid from the master cylinder (brake fluid reservoir) to the brake calipers or wheel cylinders.
When you apply the brakes, brake fluid causes the brake pads to press against the rotors, making the car to slow down or stop. If brake fluid is unable to flow correctly because the brake hose is leaking or cracked, the brakes will not work properly.
Brake hoses are made of rubber and it is common for a brake hose to become hard and brittle, causing cracks and leaks. When that happens, you will see fluid under your car or on the wheels. You will also observe the brake pedal is easier to push.
Facts to Note:
Your vehicle has multiple brake hoses, so it may be that only one of the hoses needs to be changed; if a hose has internal blockage, however, then all hoses should be changed.
Your brake hydraulic system will need to be flushed during this service.
How to Fix:
Inspect brake hoses.
Take out and change if cracked or leaking.
Change brake fluid by bleeding all air and contamination out of brake system.
Perform brake safety inspection.
Inspect brake system for fluid leaks.
Perform test drive.
Keeping the brake hoses in good condition is essential for your safety. Ask your mechanic to check the brake hoses every time you get a tire rotation or brake service. It is recommended that the hoses are examined every 30,000 miles or 24 months.
Common symptoms indicating you may need to change the Brake Hose:
You may see a clear fluid on the ground and around the wheels.
When you apply brakes, the pedal goes all the way to the floor.
Brakes are not working.
Importance of this service:
All services associated with proper function of your brakes are vital. In addition to safety issues, ignoring small repairs can quickly lead to more serious (and more expensive) problems.
