My old Panhead chopper is showing its age! Anything with fluid in it releases it after a while. Same with brakes. The front master cylinder fits and operates just fine. Should of gotten the switch housing too as the master cylinder is polished.

DICK on 9/27/2019

Works great just like it’s supposed to

PAUL on 9/18/2019

Due to the product having mechanical issues, this will be a two part review. The master cylinder internals are pretty much junk and should be reviewed by the quality team. On the positive side, the customer service throughout the return was positive. Your customer rep Anthony H. was outstanding in his performance throughout this event. Thanks.

ROD on 9/2/2019

Better than others I’ve seen as it come with the brake switch nice touch as they never go in or out easy

AL on 7/29/2019

Well made. Working great.

GAYLORD on 7/16/2019

Have rebuilt brakes before don't always work. Chose to buy new brake cylinder this time on 1977 Lowrider. Fits & working good.

IHOR on 7/12/2019

nice product was easy to put on bike

ALAN on 6/18/2019

Just what I needed, well made and working great I know because some dick head in a black Jeep didn't stop at my right of way and had to grab the front brake hard to keep from getting hit and it worked! Thanks JP!

STEVE on 6/1/2019

Fitment was great. Master cylinder works perfectly. You’ll need some pretty small wire to wire your switches. Only reason I gave it 4 stars was because the chrome went down the inside of the threads for the switch cover. I had to run a tap down each one to clean the threads. Other than that it was perfect. I would buy it again definitely for the price I’m not complaining.

stevehedman96 on 5/25/2019

Thing worked great. Only reason I gave it 4 stars was because I had to tap out the threads because I couldn’t get the hardware to thread in. Has a pressure switch inside it also! No need for one in-line now. Couldn’t be happier.
