While most of the line that contains the brake fluid is made of steel, there
needs to be a flexible section that goes from the body of the vehicle to the
wheels. This section is referred to as the brake hose, or hydraulic brake
hose. As the suspension and wheel moves round and round and up and down, so
must the brake hose from the caliper or drum-backing plate to the body. It is
of vital importance that these flexible brake hoses are regularly inspected
and replaced. This is especially true if you do brake-work yourself.
It's easy to replace the pads or other brake components and neglect the brake
hoses. Good enough is never a good call when it comes to brakes. Cracked, dry,
corroded, or flaking hydraulic brake hoses should immediately be replaced.
Another common mistake is to let the calipers hang by the hoses as work is
done on the brakes or front end. This can stress the hose where it joins with
the steel ends and cause potential rupture problems down the road. The safest
approach to working on brakes is to completely inspect everything, and make
certain all the components of the entire system are working as they should.
Hydraulic brake hoses are but one part of the braking system, yet they should
never be overlooked.
|Step 1 - Remove the wheel to gain access to the brake hose.
|Step 2 - Spray a bit of penetrating lubricant where the hose meets the
brake caliper or drum, and on any rusty clips. Go have lunch.
|Step 3 - Always use a flare nut or "line wrench" when working on brake
lines and brake fittings.
|Step 4 - Use the line wrench and a second wrench to loosen and remove
|Step 5 - Cap off any brake lines to stop leaking brake fluid. Brake
fluid will damage paint. Flush painted surfaces immediately with cool water if
brake fluid contact occurs.
|Step 6 - Remove any clips and fasteners holding the hose to struts or
|Step 7 - Install a new brake hose with new copper washers if required.
Always use a line wrench to tighten brake hose fittings.
|Step 8 - Replace any lost brake fluid. Bleed the brake system of any
air. Remove grease and crud from hoses and the disc surface with a brake parts
cleaner. Test brakes before driving.
