Default Front Brake Problem???

So i just got back from a little ride and when i pulled in my front brake was really hard to pull, like it was built up. after a while it went back to normal but now it happens every time i ride. any ideas on what it could be and what i can do to fix it??? thanks...

Sounds like your system needs a good flush. Might have some debris clogging up the pressure relief hole (the splooge hole!) in the master cylinder. If it was mine, I would dismantle the entire magillicuddy and clean the M/C, calipers and lines with brake cleaner or rubbing alcohol and blast with compressed air.

Let us know how it goes.

at the very least flush and bleed with fresh brake fluid and see what that does. if it is still bad, go to rebuild mode of master cylinder and caliper. brakes are good to have and need attention when they get wierd.

Taber......... to THE FORUM!

As mentioned.....it's time for a good look. It sounds to me like the pads may be binding on the pins. Might be as simple as cleaning them and putting a dab of never seize on them.

Before you flush and start bleeding, see if you can get to the pins, and try a squirt of WD 40 and see if that helps. If it does.....you know where your problem is.

So i figured i would bleed with fresh fluid to see if that was all it was first, i drained out what was in there and put fresh stuff in, but it wouldnt bleed. i took the hose off and found that the master cylinder isnt pumping anything through. does this sound like it would be part of the problem or a whole new one??

It is always hard to get an empty master cylinder to pump up after it is empty. Try a Mitivac bleed pump at the wheel cylinder to suck the fluid through. If your not in a hurry you can just fill the Master, hook it up and let it sit with the bleeder open for a few hours, Gravity never fails!! Once you get a drip going just bleed as usual.
