How To Remove Brake Hose Lock

Modern cars use a combination of metal lines and rubber hoses to contain and transfer the fluid that applies your brakes. The lines coming out of the brake master cylinder are made of metal to exist potent and long lasting. Metallic wouldn't exist able to cope with the movement of the wheels, so we use a safe hose that can move and bend with the pause.

Each bicycle typically has it'southward own segment of rubber hose to deal with the movement of the pause and wheel. Over fourth dimension, grit and dirt will eat away at the hoses and eventually they tin commencement leaking. Inspect the hoses on a regular basis to keep your car safe to bulldoze.

Part i of 3: Removing the sometime hose

Materials Needed

• Drain pan
• Gloves
• Hammer
• Jack
• Jack stands
• Line wrench
• Pliers
• Rags
• Safety glasses

• Wrenches

• Notation: You'll need a few unlike sizes of wrenches. I is for the connectedness going into the caliper, typically around 15/xvi mm. Y'all'll need a wrench for the bleeder valve, typically 9 mm. The line wrench is for the connection from the hose to the metallic brake line. These connections tin be tight if they haven't been changed for a few years. If you apply a normal, open-ended wrench to loosen them, in that location is a good chance you lot'll round off the connections which will mean much more work. The flares on the line wrench make sure that yous take a nice, tight grip on the connectedness while loosening and then that the wrench doesn't slide off.

Step 1: Lift the motorcar onto jack stands. On a flat and level surface, jack the car upwardly and place information technology on some jack stands so information technology will not fall while the wheels are removed.

Block off whatever wheels that are left on the ground if you are non replacing all the hoses.

Step 2: Remove the wheel. We'll need the wheel out of the manner to access the brake hose and fittings.

Step 3: Cheque the brake fluid level in the master cylinder. Make sure you have a proficient corporeality of fluid in the reservoir because fluid will start leaking as before long as the lines are disconnected.

If the master cylinder runs out of fluid, information technology will accept longer to fully bleed the system of air.

• Note: Be sure to put the cap back on the reservoir. This will greatly reduce the amount of fluid that comes out of the lines when they are disconnected.

Step 4: Use your line wrench and crack open the height connection. Don't undo it completely, we simply want to be able to unscrew information technology quickly subsequently on when we actually take the hose out.

Lightly tighten it once more so fluid doesn't leak out.

• Tip: Loosen the connection while it is still mounted. The mount is designed to prevent the hose or connection from twisting and it volition hold the connexion in place while you loosen it.

• Tip: Use some penetrating oil if the connection looks muddy and rusty. This volition greatly help getting the connections loose.

Stride 5: Fissure open the connection going into the brake caliper. Over again, don't unscrew it all the manner, we just want to make sure it will come out easily afterward on.

Step vi: Remove the mounting bracket clip. This small-scale metal piece should just pull out of the subclass. Don't bend or damage the clip otherwise you'll have to supplant it.

• Note: At this point, brand sure your drain pan is set up underneath and have a rag or ii nearby to help with any spills for the adjacent few steps.

Step 7: Unscrew the peak connexion completely. The peak connection should come up undone with no trouble since nosotros've already cracked it open up.

Remove the connection from the mounting bracket besides.

• Note: Brake fluid will start coming out as soon every bit it's open a picayune bit so accept the drain pan and rags prepared.

Step viii: Unscrew the hose out of of the caliper. The whole hose will rotate and can fling brake fluid around and so make sure you have prophylactic glasses on.

Make sure no fluid gets onto the brake rotor, pads, or paint.

Take your new hose set up to get as we want this transfer to be quick.

• Note: Brake calipers tend to be very muddy so use a rag and make clean the area around the connection before undoing information technology completely. We don't want any dirt or grit going into the caliper housing.

Part two of three: Installing the new hose

Step ane: Screw the new hose into the caliper. Y'all'll put it together the contrary way y'all took it apart. Screw information technology in until it bottoms out - don't worry nearly tightening information technology yet.

• Warning: Be careful when threading the connections. If you damage the threads on the caliper, the whole caliper will need to be replaced. Go boring and brand sure the threads are lined up properly.

Step 2: Reseat the elevation connection into the mounting bracket. Line upwards the slots and then the hose tin can't rotate.

Don't put the clip back in only yet, nosotros want some play in the hose so nosotros tin can get everything lined upwardly correctly.

Step three: Retighten the nut on the top connectedness. Apply your fingers to get information technology started so a line wrench to tighten it slightly.

Footstep 4: Employ hammer to tap in mounting clips. You don't need a sledge, but a piffling weight can help get these on easier.

A couple light taps should get information technology back into place.

• Warning: Have care not to harm the lines when swinging the hammer.

Step 5: Fully tighten down both connections. Use 1 hand to tighten them down. They should be snug, not as tight equally possible.

Pace half-dozen: Use a rag to clean up any left over fluid. Restriction fluid can damage other components, namely rubber and paint, and so we desire to make sure nosotros clean everything.

Footstep seven: Repeat for all hoses that need to be replaced.

Part three of 3: Putting everything back together

Step 1: Check the fluid level in the master cylinder. Before we start bleeding the arrangement of air, we desire to make sure we have a good amount of fluid in the reservoir.

The level shouldn't be besides much lower equally long as your transfers were quick.

Step two: Bleed the brakes of air. Y'all should only have to bleed the lines that y'all replaced. Bank check the fluid level subsequently haemorrhage each caliper and so that you don't run the primary cylinder dry.

• Tip: Have a friend pump the brakes while you open up and close the bleeder valve. Makes life much easier.

Pace three: Cheque for leaks. With the wheel still removed, pump the brakes hard a few times and audit the connections for whatsoever leaks.

Step 4: Put the bike back on. Make sure yous tighten the bicycle to the correct torque specification. This can be found online or in the owner'south manual.

Step 5: Fourth dimension for test drive. Exam the brakes in an empty street or parking lot first before going into traffic. The brakes should feel hard since we only bled the organization. If they are soft or spongy there is probable notwithstanding air trapped in the lines and you'll need to bleed them again.

Replacing the hose typically doesn't require any expensive special tools, so you tin can save yourself some money by doing the piece of work at dwelling. If you lot are experiencing any difficulties with this task, our certified technicians are always bachelor to assist you.
