Part: Honda CB360 / CB450 / CB550 Replacement Master Cylinder

Why You Need This: Sometimes the master cylinder on your Honda CB360, CB450 / CB500T and CB550 just can not be rebuilt. Years of sitting in ancient brake fluid have turned its once mighty stopping power into aluminum dust. Worry not as our high quality replacement brake master cylinder comes ready to be mounted with the correct look and feel for your Honda CB360, CB450, CB500T, or CB550. The master cylinder has a 14mm piston, like the original factory unit, with the brake lever included.

While you are overhauling the front brake on your Honda make sure to change out the brake hoses, hard line and rebuild the caliper.

Note: This master cylinder is not visually identical to the factory unit but looks very similar. It does fit and perform just like the original.

Installation Tip: Always use fresh brake fluid from a sealed container. Start the bleeding process with the hard line disconnected from the caliper. Purge the line until all the air is gone from the system then connect the line to the caliper and finish the bleeding process. Using a speed bleeder will make the brake bleeding process much easier.

Well boys, I would love to be able to tell you that here in Iowa I have been in the detached, unheated garage getting the rat ready for the road this spring. Alas, the parts are here in a box on the office floor waiting for me to take them out and assemble them. I must say that I do take the beautiful new master cylinder out and mime running the road while sitting here at the office desk. But sorry to say, my old bones and feeble circulatory system keeps me from braving 25 degrees in the garage to assemble them and so I must content myself to peruse vintage Honda posts on Facebook or drool over the pretty rebuilds on Bing search. Winter's a harsh mistress here in the Midwest and your just gonna have to wait until spring for a more suitable review. Thanks boys, keep up the good work!

Great for Converting to Disk
I am adding a 1975 disk front end to my 1974 CB360 (originally drum), and got this product to complete the conversion. It's a great product, and was a very easy install. I've also replaced the caliper and got all new brake lines.

Great part, but a little difficult to bleed. I finally gave up on the original 1972 master cylinder on my CB500 and got this one to replace it. I also got new brake lines, banjo bolts, and crush washers to go with it. The new parts fit perfectly and now work great, but I had a tough time bleeding the whole new brake system. I had to bench prime the cylinder and use a vacuum pump to get all the air out. Once I got to that point, the brakes work perfectly. But that was probably me more than the parts. I'd definitely recommend the brake cylinder and power lever. Another great product, as usual, from CMC.
