Help Front brake locking help!!!

[Adan_b]

My 2001 yz 125 front brake will gradually apply the by itself, and after about 5 min of riding my front break will be completely locked up but if I leave it there sitting after about 5 min they will slowly un apply themselves

Just keep in mind that this all happens without me even touching the brake at all the whole ride but they will still gradually apply 100% by themselves

It sounds like you have have water in your fluid. When is the last time it was changed? It should be done once a year. Water expands when it gets hot and with just the pads riding on the rotor it can get hot even if you don't apply the brake. The hotter it gets, the more it expands and pushes the pads into the rotor.

I bought the bike about 2 weeks ago so I’m not sure how long it been since it’s last changed. But I will give it a try and hope it works
