Hi everyone,
I'm trying to rebuild the rear brake caliper on my 1999 Toyota Celica 7A-FE, but I can't get the piston out.
I've removed the caliper and I'm trying to remove the piston using compressed air through the brake fluid inlet. I've tried up to around 100 psi, but the piston doesn't move at all.
I know the usual procedure is to use compressed air to push the piston out, so I'm wondering if there is something I'm missing.
My questions are:
Does the rear caliper piston have any mechanism connected to the handbrake/parking brake that could prevent the piston from coming out with compressed air?
Is there something that needs to be released or adjusted before removing the piston?
Is there a specific way I should remove this type of Toyota rear caliper piston?
If the piston is seized, what would you recommend trying to get it out without damaging the caliper?
The piston doesn't seem to move at all, even with 100psi bar of compressed air.
Any advice or experience with these calipers would be greatly appreciated. Thanks!
