Brake hose kit for the Honda CB450/CB500 and CB550 models from the 70's. This kit fits the stock handlebars (approx. 3 - 4.5" rise) for the models listed below. We recommend measuring your upper line to be sure it will reach your bars, it is common to have non stock handlebars.

If your brake lines are original they should probably be replaced..... It's one of those things you've been meaning to do, now's your chance!

We have banjo bolts available separately so you can choose your color!

Note: The lower hose in this kit is 1.5" longer than the original hose on some model years. It can work on the 1977-1978 CB550K but measure your upper hose length first.

Kit Contains:

Upper Brake Hose - 15.5" - Connects between the master cylinder and the 3 way joint under the headlight (the joint with the brake switch on it).
Lower Brake Hose - 14.5" - (threading 10mm x 1.25mm) Connects between the 3 way joint under the headlight and the metal hose that attaches to the front brake caliper.
Brake Pipe - Hard-line that connects between the lower brake hose and the front brake caliper.

    I bought this hose kit to replace the original lines for my 1976 CB550. I have lower Norman Hyde M Bars on the motorcycle. Everything fits great.

    Not much to say other than it worked just like stock and looks perfect. 5 stars. I buy 90% of my parts from 4into1. I can always count on quality.
