Needed a new caliper so instead of over paying for OEM and service got this instead, and it was I believe a seamless install. It was my first time replacing the whole caliper assembly and it is pretty much a plug and play thing. The only thing I noticed was straight out of the bag one of the caliper rail bolts was over torqued. Fearing destroying another caliper I just took off the other side which came off with a bit of elbow grease.
Initial 2 Week Review
Overall, these seem like well re-built calipers. They are a great price but remember it will cost you about $40 to send the old calipers back to recover your $50.00 core. In my opinion not worth sending them back. A re-build kit costs $5-$10 for the boot and the O-ring, plus some elbow grease.
