Seized calipers twice now

[COMpulse]

2015 SHO with 90K Miles.

Rear calipers seized around 75,000 miles. I had brakes and suspension done. Now seized rear calipers again at 90,000 miles.

Anyone else had similar issues? Driving a car with a tune isn't as much fun when your brakes are locked up.

Possibility... The flexible brake lines (hoses) could be collapsed. You create enough pressure to push fluid past the blockage, but the caliper doesn’t have enough power to push fluid back past the blockage. Hence you get a seized caliper.

Regarding above, after 7 years, replacing those hoses should be cheap and not a terrible idea even if they are not the current issue. They all degrade at some point and it's usually internal failure that you often can't spot. I've had this happen at least twice with older cars.

Check your parking brake cables. I thought I had seized rear brakes and it turned out that the cables weren't fully returning.

Thanks for the tips! I will look at the brake lines and the parking brake cables.

An easy way to check for a collapsed brake hose is to open the bleeder screw while attempting to compress the "seized" brake caliper. If the caliper compresses easily with the bleeder open, the caliper is not seized and chances are quite good the brake hose is the issue.
