Caliper Unsticking Advice ?

So tomorrow I'm going to do some work on the green 99, which have grabby brakes. Oil change, coolant, spark plugs wires, etc.

Any advice on how to unstick sticky calipers? Let to my own devices I would spray them with PBBlaster and hit them with a hammer until they cry uncle.

Is this good or bad?

Eventually the whole brake system is in for a rebuild. I'm just trying to get the car mobile at the moment.

you mean unsticking the caliper piston?

i always either pulled the caliper but left the hose attached and pumped untill it popped out (messy)

or pulled it and shot compressed air in untill it popped

It's probably just all stuck due to rusty rotors. You can replace them and the pads and they will probably correct the issue. You could also try driving it around for a few hundred miles, that might free things up too.

hitting brake surfaces with PB blaster is the worst thing you could do if you want the brakes to work, though it probably sure would free them up.

No packing tape on this car, ok?



I would just try driving it, like stated above. The brakes on the 86 were crap for 2-300 miles then all of the sudden they felt great.

Then I found out that everything was rusted on...

Anyway, drive it for a little bit every day around town until you trust it.

Also, stop using the parkig brake on the off chance that it has anything to do with it!
