You should gaze the brake line pipes and hoses every six months for damage. Casual problems on hoses build in hardness, cracking, fraying or chafing. Pipes can suffer exclusively from corrosion and dents. Any damaged components longing to be replaced, though a minor corrosion can simply be scraped off. Generally, hoses Testament extremity replacement and Frequently than pipes.
Preparation
To prevent loss of fluid when removing the lines, siphon absent the fluid from the crackerjack cylinder using a siphoning thing or Disinfected, unused turkey baster. You can too remove the reservoir cap and seal the opening with cellophane to prevent air from getting in (this won't completely prevent fluid loss however Testament detain it to a minimum). Clamping the hoses shut Testament aid so faraway as they are much attached; benefit a twosome of self-locking pliers or brake hose clamps and area them as quick to the drainpipe as you can. Disinfected absent all dirt from the ends of the hoses to carry it from getting inside the hoses during Emigration.
Removing/Replacing the Lines
The brake lines are recurrently connected to the hoses with two union nuts. Grab the stone at the hose's cusp with one wrench to dominion it in apartment while you turn the follower at the conduit's head with another wrench. Bag shine follower wrenches to avoid stripping the nuts at their corners; this isn't as relevant provided the pipes are vitality replaced.
Once the nuts are loosened at both ends of the conduit, pull gone the retaining clips attaching it to the Trimmings to remove the cylinder.
Whether you are removing and replacing a hose, disconnect the banjo bolt attaching it to the caliper at the hose's other borderline. You Testament use the same bolt when connecting the new hose but with new sealing washers.
When replacing the brake line pipe, use prefabricated steel pipes (not copper) from an auto parts store. If the pipe needs to be bent before installation, use the old pipe as a guide and bend with a proper bending tool. Fit the pipe into the retaining clips at the fittings and tighten the nuts. Make sure the hoses are not twisted or kinked at all and both the pipes and hoses are clear of any moving or heated parts on the vehicle.
Bleeding
You must bleed the brake system of air after working on the lines. Make sure the master cylinder reservoir is filled first. Refill the master cylinder reservoir with fresh fluid after bleeding all four brakes and make sure the pedal feels firm and not spongy. While another person pushes down on the brake pedal, turn the bleeder screw more To admit air and fluid to flow through the tube. When you get a clear stream of fluid, close the valve.
Start this procedure with the right rear wheel and then move to left rear, right front and left front. There is a bleeder valve on each caliper. Remove the cap on one caliper's valve, turn the valve screw slightly and place a piece of clear tubing on the valve. Place the tubing's other end inside a clear container partially filled with brake fluid.
