Mastercylinder or wheel cylinder or caliper piston?
If it's a mastercylinder, toss it and get a new one.
Wheel cylinder, squeeze the brake shoes together, if it won't move, toss it.
Caliper piston, use a c-clamp and compress it. Now keep in mind. If it is a rear wheel caliper and it has any slots, like a regular screwdriver groove, or a plus pattern. These cannot be pushed but are rotated either clockwise or counterclockwise. If it's a long slot use a flat bar or huge screwdriver, if it is 4 little cuts in the outer edge, use a pair of needle nose plyers and span the difference. Than use the tools to try turning the piston. It should move fairly easy, if not, toss it and replace. (Rotation of the piston is how the emergency brakes set)
The E brake is on?
Try turning it with long nose pliers
it wont stop. You will very likely push the seals out of the brake cylinder and have to repair or replace it and bleed the brakes
Worn master cylinder.
my guess is that it is the brake relay
Defective Master cylinder?
hi people i have a Toyota selica 98 mod ... i need to remove my bk brake disk it wont budge iv loosened the hand brake and removed calloper ???any ideas thanks odbod
My Mom had the same problem with her truck.. It is due to a recalled part that is on the brake master cylinder
because it dose not move therefore it wont budge.
The bearings are probably just stuck on the spindle, you might need a puller to help, hammering wont get it and will damage other things, it needs to be pulled off nice and slow.
Four Possible reasons... Low brake fluid - check the brake fluid level in the master cylinder Emergency brake is on - check emergency brake Low brake fluid pressure - such as a broken brake line or a bad wheel cylinder. Check the master cylinder to see if it is empty. If you add fluid and pump the pedal you will probably see brake fluid on the ground or on the inside of the tires. Possibly a bad master cylinder. - The fluid will stay full but you will have no or little brake pressure. Could be air in the system as well. BE CAREFUL If you happen to add power steering fluid or transmission fluid to the master cylinder instead of brake fluid you will destroy the system. Make sure you use ONLY brake fluid and clean the master cylinder cap off with a clean rag first so no dirt gets into the braking system.
Sounds like the brake light switch is defective.Sounds like the brake light switch is defective.
