sup people i have a weird problem with my brakes i'm not a mecanic but anyway. i was short on cash and needed to change my rear brakes,so i did myself then i bleeded all 4 of them,everything was fine until yesterday when i was on the freeway i steped on the brakes and my car started to shake so got off the freeway and my pedal got real hard as if i was stepping on the brakes then i took off and mycar started to pull and it kept pulling and i could feel the brakes on the rotors so right there i bleeded the right front wheel and it went away but today right when i got home it's doing it again what is it i will have it checked tomorrow??
