Brakes jammed on
The causes and remedy for brake jamming:
As a first aid, loosen and then tighten any one of the front wheel bleeding nipple. This will free up the brakes.
- Front calipers pins jammed. (Re-grease the pins with graphite grease)
- Front calipers pistons jammed. (Remove the caliper one by one, do not remove the brake pipe, depress the brake pedal only one time then release, lift the caliper boot at one side with abrupt tool, just as we lift up our eye lid with thumb and index finger, pour few drops of brake oil DOT 3 into the boot, push back the piston to allow the caliper to fit on pads.
- Rear wheel's pistons jammed. (Free up the pistons, inspect the brake washers, replace rear wheel cylinders if brake washers are found swollen).
- Brake master cylinder defective. The brake jamming problem often arises when the brake master cylinder washers swell up due to aging or using wrong grade of brake oil. In such cases the washers expand and block the return line of the brake oil. If so, replace the brake master cylinder with original one.
