Chevy Lumina, Brake Woes and Support Groups
problem ( I was told) is that the rear disc calipers are frozen on my
"93 Chevy Lumina. The shop told me I need to replace the calipers,rotors,pads,
and hoses for a grand total of $450. My question: is there any way of
freeing up the calipers? Do I really have to replace the rotors and pads
(neither of which look in bad shape, rotors rusty but not pitted. Any
should be a support group for owners of vehicles with this braking system.
I'm not kidding. Your vehicle is notorious for rear disc brake caliper
problems. Unless you are skilled at rebuilding disc brake calipers, the
only solution is replacement. If rotors are rusty they must be re-surfaced
or replaced. A rusty rotor does not provide the correct braking surface
for safe and effective operation. The only consolation to your dilemma
is that you're not alone.
