    Brake Caliper removal

    Trying to remove the Caliper but having trouble removing it?

    Took out the 2 caliper bolts and it moves but not by much?

    Haynes manual says pull it out but its not moving?

    OK pads now off and one side was really bad not a drop of pad left on it and its been grinding the disc for some time now, Piston seals got a hugh hole in and its probably ****ed.

    What can I do about it?

    Also that shitty little torx screw hold the disc is welded on and it starting to round off?

    Help!

    Hi,
    you need a new disc if it's that damaged, buy a pair they are cheap enough. Don't worry about the seal, it's only a dust seal. Don't worry about the torx screw - the wheel holds the disc on, just drill it out.

    So the seal is just for keeping dust out?

    Pushed the good piston back in and the brake fluid is high, would this stop me pushing the other piston back in? Tried with g-clamp but not much movement?

    If I lift the brake fluid lid off with that release pressure or should I clamp the brake line and bleed off some fluid??

    Hi,
    If the reservoir is full it won't stop the piston moving, it would just push fluid out. It may be best to take some fluid out just to stop it dripping fluid everywhere. Put a pad in the good piston side to stop it coming out too far, and try to push the seized piston in. If it is really stiff try easing it by pushing it in a bit then push it back out with the pedal - just a bit - and lubricate it with brake fluid. If the piston won't free off you will need to get another caliper from a breakers.

    Tried to push piston back and it's seized!
    The hole in the seal has just poured out all the brake fluid, this happened when I pressed to brake pedal to move the piston while off the disc hoping I could move it back?

    Hmm looks like you might have blown the seals... might be able to recover it but other than that its gonna need a new seal set and rebuild.

    Hi,
    It sounds like the piston has come out of the caliper. Take the outer seal - the dust seal off, and have a look. It will push back in again but you need to push the piston in dead square to the hole or it will tilt to one side and jam. If there is enough room take the piston completely out first, clean it up and the inside of the caliper, and check the main seal isn't damaged and is sitting firmly in the groove.

    If I get caliper off ebay do they all fit? 98-04 4 stud.
    Does ABS make a difference to design of the caliper?

    Cheers Paul

    Richard btw do you know how to change timing belt??
