snapped a bolt and its stuck

[rojoor]

guys on my 180sx, i snapped the bolt where the screw holds down the spark plug case.... the screw is stuck in there... wot can i do? is there a place where i can take it so they can take the broken bolt out? thanx

also i tried to change da break pads but i couldnt push the piston back in... is there a tool i can use?

for the brake piston, try releasing the bleed nipple to relieve the pressure. A big screwdriver or similar is usually able to force the piston(s) back - do one side at a time, then fit new pad, because pushing the opposite piston back (in) will simply push the (now) opposite piston back out.

For the bolt, your local mechanic should be able to extract it with an 'e-z-out'.

Are you trying to change the front or rear pads?

Front: use a G clamp to push them back in.

Rear: Need to rotate the piston not push it straight back in.

You could try with a ez-out screw extractor, except they do seem to like breaking. Even more of a bitch of a job to remove a broken ez-out than a broken bolt. (They are made of hardened steel)

use a g clamp for the front....cant you just use a screw driver to lever the pistons back in then undo the bolts and pull out the pads? thats how i used to do it on fords when i used to service them..

"Front: use a G clamp to push them back in.

Is this one for 180sx? Does it apply to Skyline R33?

I think its been worked out elsewhere that you only screw the piston in if the caliper incorporates the handbrake. Otherwise, it simply pushes in.

Applies to all calipers, AFAIK
