have to push the back brake really hard to lock it up

[gokitty199]

any idea how i can fix this, when i go to lockup my rear break or even slow down i have to put a ton of weight on the rear brake lever, it takes alot of force to even move the lever down. also anything i can do, my front breaks squeak whenever i use them even if their not hot

my 2014 kx450 brakes squealed. I tried different pads and but could not get rid of the sound. IN the end I swapped out the rotor for a floating rotor and that finally fixed it. I've never had that issue you mentioned about the rear brake. Have you tried bleeding out the system? is your linkage adjusted correctly?

The factory brake line can swell over time and lose hyrdraulic pressure. Swap it out for a stainless braided line. I believe the cheap Tusk ones are made by Galfer.

I would check the brake pad pin. They get notched over time and the pads get hung up on them needing excessive force to get over the notch and engage the disk. A new pin is only a few bucks.

first bleed it out there might be air in the system then do what woods rider recamends check the brake pin

will do once i test it again, i took a paper towel and wiped the entire rear and front rotor and there was grease on it, i guess from when they ship the bike so in the next month or so im gonna see if that was the cause.

Yeah grease is no good on the rotor.  Just ride it now and brake a few times to scrub it off your pads.

If you want to get rid of the squeal, try soaking the pads over night in rubbing alcohol and rubbing the rotor down with a brand new scotch brite pad and alcohol again. let them dry for a day or so and see how it works.

I use this all the time for my mountain bikes and it hasn't failed me yet.
