Sounds like you need to bleed the brake system.

SOURCE: 2004 electra glide classic front brakes locking

By "locked up", I'm assuming that once you release the front brake lever, the bike will not roll. As with all disc brakes, the brake pads do not withdraw away from the disc. They maintain light pressure on the disc to keep it clean and dry. When you pull the lever, they apply stopping force. When you relaese the lever the force is releaved but the pads still stay in contact with disc lightly and the wheel will turn.

If you've tired another master cylinder and the brakes are still locking up, there is something wrong with either the hose or the caliper itself. Usually, it's the caliper. You must take the caliper off and use compressed air to get the piston out. You must be very careful while doing this. If you must use high air pressure, the piston will come out of the caliper with extreme force. I use a small air pressure regulator to slowly increase the pressure starting at about five psi.

If you get to 25 psi or better, things can get dangerous. At this point, I quit using air pressure and go to a grease gun. By taking the end off the end of the hose on the grease gun, it will screw right into the place where the brake line goes most of the time. Now pump the grease in until the piston pops out. It's a nasty job but a lot safer than the air pressure method. Clean the caliper up completely free of grease. Use a wheel cylinder hone to hone the inside of the caliper's piston bore. Pay particular attention to the groove where the caliper top seal goes in. Lubritcate the piston and the inside of the piston bore of the caliper with the proper type of clean brake fluid and press the piston into the bore. The caliper is now ready to reinstall. Make sure you are using the proper type of brake fluid. Harley changed back to DOT 4 brake fluid but I can't remember what year. It should be on the top of the master cylinder cover. Do not mix DOT4 and DOT 5.

I have on a few occasions seen a rubber brake hose that would not allow the brekes to release. They get damaged on the inside. The very high pressure present when you apply the brakes can get past an obstrucion on the inside of the hose. But, once you release the pressure, as the pressure lowers, it gets to a point where it cannot get past the obstruction and thus holds this amount of pressure on the caliper. Replace the brake hose.

Make sure you bleed all the air out of the system. If you leave any in there, as the air heats up, it expands and applies pressure to the brakes and makes them drag. Alweys test the brakes before riidng the bike. Improperly serviced brakes can cause serious injury or death. Good Luck, Steve

SOURCE: HARLEY- 02 DYNA WIDE GLIDE

WD4ITY has no clue what he in talkjing about in regards to starting the bike or moving it has no effect on brakes loosing pressure. I for one have this EXACT same issue. I can bleed the brakes to where they are rock solid, and while sitting still the brakes are rock hard. The moment I move the back backwards or forwards even the slightest bit, the brakes loose all pressure and the handle moves to the grip. It's due to the front rotor being out of alignment or at an angle in comparison to the brake caliper. When you move the bike forward or reverse the rotor is pushing the pads apart causing your handle to have a no pressure effect since you must now squeeze it a few times to regain pressure. On my FXD this was caused by the front wheel not being spaced properly causing the forks to come in at the bottom causing a slight rotors out of angle effect. I did notice a starting effect where I would loose some pressure, but I accounted this to me sitting on bike, lifting it up straight which caused the rotor to push on pads which in turn made me thing starting caused the loose of pressure. Don't always believe what people type on the internew telling you that moving a bike has no effect when it in fact does and any Harley tech or sport bike tech for that matter, worth their salt should tell you this same thing.

SOURCE: new master cylinder and brake line on 2002 wide glide no brake preasure wheel turnes no brake preasure what next

First thing, is the bleeder valve on the caliper at the wheel in the high position?
If it's on the lower part of the caliper, air will be trapped above it.
Sometimes, a brake vacuum bleeder works better than the traditional way:

After bleeding all the air you can, leave it overnight with the pedal/lever (you didn't state if the front or rear brake) tywrapped in the ON position overnight.

IF it's the rear brake, make sure there's a slight amount of play before the rod to the pedal engages the master cylinder piston (if not, it won't allow the piston to fully return).

No front brake preasure on 2002 wide glide


Sounds like the master cylinder is defective or you need to bleed the system. Did you possibly add in the wrong type of brake fluid and destroy all rubber components in the sytem???

NO BRAKES WHEN ENGINE IS RUNNING


Brakes and engine are totaly diferent systems. Do you have brakes when engine is off? If so the only conection between engine and brakes could be vacume which is created by the engine stored in the chamber at the master cylinder to assist with brakes but does not overide personal brake presure only help increase braking. If trully you have less breaking preasure with the engine running then check the vacume line at the master cylinder to see if there is a vacume or maybe preasure?

2001 hd dyna wide glide brake light does not come on when brakes are applied , tail light works,bulb is ok , is it the brake sensor ,where is it located and what does it look like thanx


Your Wide Glide has two brake light switches. One is in the right handlebar switch housing and operated by a tang on the front brake lever. If it's not working you probably have a bad switch up there as well. The rear brake switch is underneath the bike. Find the metal line coming out of the rear brake master cylinder. Follow this line back towards the rear brake. You should find a "tee" fitting with a small switch screwed into it. It'll have two wire plugs with about four wires on it unless they've changed something. You'll know it when you see it. Replace this switch first. Since the front brake light works off this switch as well, it may fix the front brake light switch as well. If not, you'll have to take the right handlebar switch housing apart to get to the front switch.

Good Luck

88 t-bird non abs. the front brakes drag. i have replaced all rubber lines also new master cyl. new front brake calipers. rear brake hose preasure will bleed of after it has set for 15 to 20 min.can...


This is bizarre... I'm suspecting dirt in line(s). Are you bleeding correctly? Starting w/ Right rear, left rear, right front, then left front. You might try using a power bleeder also. A possible long shot, is brake proportioning valve sticking.

The rear brake light on my 2001 wide glide does not not work when applying the brake. I put in a fresh oem 2 filament bulb to replace a burned out one and now the light is on but the brake function is not...


If you're sure the bulb and socket are alright, there are two brake light switches. The front brake light switch is located inside the right handlebar switch housing. To get get to it, you have to disassemble the switch housing. Loosen the two bolts that hold the front master cylinder on and slide it towards the center of the handlebars. Now, take the two bolts that hold the switch housing halves together out. Carefully seperate the two halves. There are lots of wires in there. You'll have to loosen and remove both the throttle and idle cables to get the throttle sleeve and right grip off the handlebars. Now, the lower part of the switch housing is loose and you can get to the brake light switch that sticks out of the switch house towards the Front master cylinder. If you desolder the wires, you can replace the switch, resolder the wires. Put the switch housing back together being careful not to pinch any of the wires. Reassemble and adjust the thottle sleeve and check for the proper operation of the throttle.

The rear brake light is controlled by a rear brake pressure switch located beneath the bike. Find the rear master cylinder and the metal brake line that comes out of it and goes towards the back of the bike. Follow the line and you'll find a tee with the switch in it. Simply screw the old switch out and screw the new one in. Do not depress the brake pedal with the switch out of the line.

Make sure you do these jobs correctly. If the throttle doesn't snap shut, work with it until it does. Check the brakes and make sure they work. If the throttle or the brakes do not work as they should, you could lose control of the motorcycle and suffer severe injuries or death.

2006 fxdwg break light stays on whether breaks are in use or not happen whether bike is running or not. Dont know what the problem is all other lights function correctly


Ok the problem is probably in the front brake light switch. Loosen the bolts that hold the front master cylinder on the handlebars and slide the assembly as close to the right handlebar switch housing as possible. If this does not put the light out, then your front brake light switch is probably defective and needs replacing.

Good Luck
