What size are the bolts on a Silverado caliper?
The standard bolt size used on Silverado calipers is 14mm. This size is commonly used for the caliper mounting bolts that secure the caliper assembly to the vehicle's brake system.
Detailed Explanation
The Chevrolet Silverado is a popular full-size pickup truck that has been in production since 1999. Like most vehicles, the Silverado's brake system utilizes calipers to apply pressure to the brake pads, which in turn press against the brake rotors to slow and stop the vehicle.
The calipers on a Silverado are typically secured to the vehicle's suspension components or brake mounting points using a series of bolts. The most common bolt size used for this purpose is 14mm.
- The 14mm bolt size provides a secure and stable connection between the caliper and the vehicle's frame or suspension.
- This size is chosen to ensure the caliper remains firmly in place during normal driving conditions, as well as during more demanding situations like heavy braking or off-road use.
- Using the correct 14mm bolt size is important for maintaining the integrity of the brake system and ensuring safe, reliable braking performance.
It's worth noting that while 14mm is the standard bolt size, there may be some variations depending on the specific model year, trim level, or even the region where the Silverado was manufactured. Always refer to the vehicle's service manual or consult with a qualified mechanic to confirm the correct bolt size for your Silverado's caliper.
What size socket for brake caliper bolts?
The socket size for brake caliper bolts varies by vehicle, but common metric sizes are 13mm, 14mm, 15mm, 17mm, and 18mm. Caliper bracket bolts can also be a different size, such as 18mm or 19mm, and some cars use specialty sockets like Allen (hex), Torx, or 10-point sockets. Always check your vehicle's service manual for the exact size.
