| Description of the problem | Rear brake calipers have seized at least 7 times, causing me to need to replace them. I'm at 115,000 miles and have had the left one seize, destroying the rotor and pad 4 times, and the right one seize 3 times (once recurring within 15,000 miles of replacement). The car has been repaired at different shops, but the problem keeps recurring. First time occurred shortly after 30,000 miles. Occurs every 1-2 years since then. Most recent occurrence is now (car is being repaired this morning, left rear caliper/rotor/pad). Noticed massive shimmying this time. Previous times have been noticed from: grinding noise, car won't accelerate over 10 mph (locked in engaged brake mode that time), and severe bucking while being driven. |
