i just got my 1st civic the other day. its a 93 with the 1.5 my front brakes keep locking once it gets hot im running out of things to replace. so far ive replaced the calipers master cylinder and the brake hoses. its still locking. im thinking its the proportioning valve. help any one?

 

Adjust the brake pedal / booster. If the master cylinder doesn't return to the full out position when the pedal is not pressed, the brakes will gradually drag and lock.

Try just moving the brake light switch so the pedal comes up higher. If that doesn't let it come up higher, adjust the nut on the inside (brake pedal side) of the booster. Also I think the pin on the output side of the booster that presses the master cylinder is adjustable.

 

i adjusted the brake pedal. new to these hondas what would be the simplest way to adjust the booster
