What happens when caliper seizes?
In most cases, a seized brake caliper manifests itself as reduced braking power. Usually, when a brake caliper seizes, the brake pad on the side of the caliper piston will wear excessively. Eventually, the brake pad will wear down so much that it can affect the brake disc which will get damaged.
Is it safe to use a seized brake caliper?
Once that has occurred the caliper is no longer safe as it will be apt to leak at the seal and be prone to seizing. And brakes is one area where it is better to be safe than sorry. Many years ago I rebuilt calipers and have dismantled seized calipers and the un-seized caliper from the other side and usually found similar damage to both sides.
What causes a brake caliper piston to seize?
The reason caliper pistons seize is from brake fluid contaminanted with moisture. So if the caliper piston is seized, replace the brake fluid. I’d replace both.
Can a Cheapo non OEM brake caliper be replaced?
It depends on whether cheapo non-OEM brake components have ever been used on this car.
Do you need to replace the caliper pad?
If the pad that is worn down is the outer pad, the the caliper seized because of the bushings (aka pins but Toyota calls them bushings). Neither caliper needs to be replaced but the bushings on both sides at the very least need to be removed, cleaned and re-greased. Sometimes it is best to just replace the bushings, they don’t cost that much.
What should I do if my brake caliper seizes?
If the piston is seized in the caliper then the caliper requires replacement. If the caliper piston is seized then I would replace both calipers. The reason caliper pistons seize is from brake fluid contaminanted with moisture. So if the caliper piston is seized, replace the brake fluid.

What happens when the caliper slide pins seize?
If it is the caliper slide pins that have seized, the car may appear to drive normally, but the pads will only be pushed onto the disc from the piston side. This will give reduced braking ability on one wheel, and wear the pad on the piston side much faster. In cases like these, the car may pull to the opposite side when the brakes are applied.
When to use handbrake or front brake caliper?
The handbrake prevents the car from rolling when the car is at a complete halt. In extreme circumstances, the driver can use the handbrake to stop the car when the brakes fail. The front brakes often play a greater role in bringing the car to a halt than the rear ones. This does not mean you should replace one and ignore the other.
