- Spongy brakes
- Low fluid level in Master Cylinder reservoir
- Wet spots on driveway and/or parking area
- Dampness on back of drum brake or caliper
- Typically within 5 to 6 years of service.
- A slow leak in a brake hose can, over time, lose enough fluid to allow air to enter the hydraulic system which will increase the amount of pedal travel to apply the brakes.
- A hose's performance can be jeopardized by an external leak, internal malfunction or age / deterioration.
- Internal malfunctions can cause a small part of the inner hose liner to become dislodged and act like a one way check valve that will either prevent full brake pressure from getting to a wheel or not allowing the brake pressure to bleed off.
- Either condition will cause uneven braking, exhibited by a 'pull' to one side or cause the wheel to drag and not fully release.
- Rubber brake hoses need to be inspected for age cracks, bulges, swelling or other damage. Brake hoses must withstand pressures that can range from a few hundred pounds per square inch up to almost 2000 psi! If a line or hose can't take the pressure and fails, all braking ability in the affected brake circuit will be lost.
The arteries of a car's brake system
A multi-braided PVA hose reinforced to be compatible with most non-petroleum based brake fluids. A hydraulic brake hose carries fluid pressure from the Master Cylinder, through a steel line at the vehicle frame, to the brake caliper or wheel cylinder at the wheel. A brake hose must flex with wheel and suspension movement.
This flexible hose connects the brake caliper to the steel brake line of the Master Cylinder.
