When you are doing a simple brake job, the last thing you want is some unexpected headaches. That can easily happen though, if a bolt is cross threaded, stripped, or broken off in the caliper carrier, your vehicle can be completely undriveable until it's fixed. The slide pins of the carriers can also become corroded and damaged, not allowing your calipers to glide as intended. Don't take a chance on a shoddy repair when it comes to a system as important as your brakes. Replace your caliper carriers and get your vehicle back on the road.If it's time to replace your caliper carriers, also consider replacing your rotors, calipers and pads. ECS Tuning carries a wide variety of stock replacement and performance pads to restore or upgrade braking performance. Keep your braking system in top notch condition by checking and replacing components whenever wear is visible or suspected. This caliper carrier is designed for vehicles using 312x25mm front rotors. It can be used as an OE alternative or to upgrade to the larger 312mm rotor size from smaller brakes.
