I think your rear master cylinder is 5/8" in diameter since it is only a single disc in the rear brake. Dual disc front brakes usually have the larger 3/4" diameter master cylinder. If you take the master cylinder apart, you can either measure the bore or look on the rubber "cup". The size is usually on the cup.

I am building a trike from a 1998 Harley Davidson FLSTC Heritage Classic. I want to make the front and rear brakes work on one master cylinder. My idea is to use the rear foot brake master cylinder wi

First, for this to work, you'll need a "proportioning valve" to adjust how much pressure goes to the front, and how much to the rear.

Also, you'll probably need a master cylinder with a larger bore than the stock on, to push more fluid.

Rear caliper sticking on rocker fxcwc

Hi Anonymous, and the usual suspects are:
1. Brake disc badly worn or warped.
2. Insufficient brake pedal freeplay.
3. Brake caliper pistons/bore contaminated or damaged.
4. Master cylinder piston not returning all the way.
5. Brake line inner liner collasped
6. Dot 3 used in a Dot 5 system
Good luck

I have a 200 heritage softail classic the brake light stays on and i dissconnected the pressure switgh for the foot brake and the light stays on. So I guess it's the hand brake switch that is shot. If...

If you disconnected the pressure switch for the rear brake and the light is still on, your deduction of a bad front brake light switch is right on. There is nothing else on the bike that would make the rear brake light come on. If you've moved handlebar switch housing or the master cylinder, make sure that they are positioned snugl against each other. Additonally, I've been reading where wear in the lever and pivot pin combine to make the switch not work. Replacing the lever and pivot pin may resolve the problem. To test, move the front master cylinder away from the switch housing and manually operate the switch to see if the switch is or is not working correctly.

Good Luck

Brake light does not work when you press the brake padel

This sounds like something wrong with the rear brake light pressure switch. Find the rear master cylinder. There is a metal line coming out of the rear of the master cylinder. Follow this line towards the rear of the bike. You'll come upon a "tee" fitting with a pressure switch in it. Check the wires going to the switch and make sure they're plugged up. If so and you still don't have a brake light, replace the switch. Simply unplug the wires, screw the switch out and screw a new one back in. Do not depress the brake pedal while you have the switch out.

good Luck
