why is it doing this

so this summer my 700xx has been having problem with the front brakes locking up even if the bike just sits the brake level will get really hard, it's like the brake system is building up pressure in itself. then if I take off the master cylinder cap the brakes go back to normal. why is it doing this?

Try just changing out the fluid if it never has been done and bleeding them.

could it be that the heat outside is expanding the brake fluid too much and building pressure in the system? cause it seems that if I was air in the system that the brake lever would be squishy all the time though.

It could be both, air in the brake line and dirt within the brake fluid. Best way is to totally drain your brake line and check for any leak and cracks within your brake hose, most off all bleed your brakes.

I wouldn't think it's air, as air normally makes shit spongy, but bleeding wouldn't hurt,
I would pull the wheels off and make sure your front wheel bearings arnt rooted, and also check one of your front rotors isn't bent, as sounds like it could be a bent/dented rotor punching on the brake pads,

If it quits when you take the reservoir cap off then take some fluid out and try it.

i have the same problem. yesterday i was out riding yesterday and at the same time the front brakes on both sides froze up at the same time. the brake lever u couldnt even pull in it was under so much pressure. i let it sit for about 10 minutes on the trail and over time the pressure slowly released. any ideas along with the others that people have already said?
