Posted: 19:58 - 28 Jan 2022 Post subject: Freeing a seized caliper. |
|
|
Just seeking some ideas and constructive input please .
I’ve managed to get the front caliper off ‘Project Scrappy Hyosung ‘.
I had to free the hose as the bleed nipple is seized solid, and I don’t want to snap it off.
After much jiggery pockery, I got the caliper mounting bolts to move and was able to remove the bolts without any damage.
The caliper still refused to let go of the disc .
After an hour of swearing, pulling, and much wiggling, it finally let go.
Now comes the really hard part , (for me anyway).
Getting the pistons out of the caliper body??
Any constructive hints, tips, or advice would be very much appreciated
Thank you ____________________ I am the sum total of my own existence, what went before makes me who I am now! |

Sirzed caliper, single piston .
Remove from stiue but don't disconnected hydraulics.
Bucket of very hot water.
Place caliper in water and count to ten then pump a few times, piston moves. Remove from water, lube piston with fluid.
Wood and g clamp, press piston back in, then repeat process. Repeat, repeat, repeat.
When confident piston is freed off, pump piston out.
Multi pistons, clamp off pistons except the one you are freeing. Don't pump out till all are free.
If piston etched or corroded, use grips. If not, don't use grips, use expanding pliers on piston internal wall, the void or saucepan cooking area wall.
For solid piston, excersize till free ( pump and clamp ) then pump out. Some pistons are plastic.
You could use heat gun hair driers...
Small rotary wire brush and drill/Dremel lubed with fluid to clean caliper seal groove and outer " land".. ____________________ nuts about bikes |
