A step-by-step guide to replacing motorcycle brake lines

  1. Check the length of your new brake lines

Before you begin the installation process, it is worth double-checking that your new brake lines are the correct length. The easiest way to do this is to compare them directly with the existing lines on your motorcycle, either by holding them alongside each other or cable-tying them together.

This may seem like an unnecessary step, but it is often worthwhile, and only takes a couple of extra minutes to complete. The last thing you want is to remove your brake lines, only to find that you don’t have a suitable replacement.

  1. Prepare for any mess

Replacing motorcycle brake lines is a messy job, even for the most skilful and experienced mechanic, and it is important to prepare for this. Be sure to cover painted bodywork before you start, thus protecting it against brake fluid damage, and wipe down the fuel tank, handlebars, and fluid reservoir. It is also worth putting a protective pan (or drip tray) under the calliper, and use a vacuum bleeder to drain away as much brake fluid as possible from the system.

  1. Remove existing brake line fittings

Once such checks and precautionary measures have been completed, it is time to go ahead and start the actual replacement process. You will first need to unscrew or unclasp any fasteners that are holding the current brake lines in place. Use a ratchet to remove all banjo bolts, wrapping each one in a rag to limit the amount of mess, and carefully feed the motorcycle brake line out of the chassis.

  1. Insert the new motorcycle brake line

Essentially, refitting a motorcycle brake hose involves retracing your steps and reversing the removal process. Feed the new brake line back into the chassis, following the exact same route as its predecessor, and ensure that each line is fitted to the correct calliper in the system.

  1. Replace and tighten the brake line fittings

The final step involves replacing the brake line fittings (e.g. washers, banjo bolts etc.) and securing them in place. It is important to take your time with this and, initially, you should only screw the fittings by hand – giving you the opportunity to check for any kinks or bends in the brake line.

Once satisfied that everything is correct, you can then tighten the brake line fittings using a torque wrench and fasten them securely in place. Finish by attaching the new brake lines to the chassis.
