Rear master cylinder harley help install

And the rear master cylinder has a fluid for rear brakes. And on the right side handlebars, you typically have a handlebar-mounted master cylinder for your front brake. It's pretty easy to swap these out. For a Lowbrow Customs master cylinder cover, you're going to be using the stock hardware and the stock gasket.

And if you want, you could swap out the hardware for some stainless steel or brass or other hardware if you want to get a lot more swanky but the stock works just fine. Use your trusty Phillips screwdriver and simply remove these two screws and the cover comes off, you leave the gasket in place.

You can see this nice warning on there. That's stupid and ugly and pointless. And then we take the nice cast, thin polished version here, which really complements the master cylinder housing very nicely. I'll just go ahead and stock hardware back in place. You might want to put a little bit of blue Loctite on these, it's your choice but that will help ensure that they don't loosen up vibrators while you're riding.

You definitely don't want to lose your master cylinder cover. And there's your brake fluid, make a mess out everything. Go ahead and get these snug and then tighten them up. And that's it. Have fun riding. You can learn more installation parts at Lowbrow Learning. You are measuring the rod to mount just like the stock one. Make sure the pedal is all the way up and the bracket to which the rod connects is standing straight.

Measure and mark, then cut to length. Next place the rod in a cordless drill. While you run the drill use a bench grinder and round out the tip. Once you have your shape, use finer sand paper and hold the sand paper in your hand and wrap around the tip and run the drill again to really smooth out the tip! Next mount the master cylinder back onto the pedal assembly. Mount assembly onto the bike, but do not mount the brake line yet!!!

Fill the master cylinder with brake fluid. Take one finger and place it over the master cylinder end where the brake line would hook up and keep pressure with your finger. Slowly push the pedal down but not all the way! Pump the pedal lightly till you feel some pressure. Let off and then just as you start to push the pedal pull your finger away and allow the fluid to escape. Before the pedal hits bottom put your finger back over the end and let off the brake pedal.

Connect the brake line. Now bleed the caliper in the same manner as the master. Push on the pedal as you open the bleeder and close before the pedal bottoms out. Tags: None. I installed a HD master cylinder on my bike and it works great, alot easier to bleed the rear brakes now. I also used a hydraulic brake light switch, no bracket needed. Ride safe. Article Tags.
