Front brakes on the 2014-2018 Silverado 1500 are one of the friendliest jobs on the truck. It is a single-piston sliding caliper on a separate cast bracket, the rotor has no retaining screw, and there is plenty of room to work once the wheel is off. Plan on about an hour per side the first time, less once you have done it.
The two things that catch people out are the caliper bracket bolts and the hub face. Those 21 mm bracket bolts are torqued around 130 ft-lb from the factory and often have thread locker on them, so a stubby ratchet will not cut it - bring a breaker bar or an impact. And if you bolt a new rotor onto a hub that still has a ring of rust and scale on it, you will get runout and a pulsing pedal within a few thousand miles. Spend five minutes per side with a wire brush.

| Dead blow or 3 lb hammer Knocks a rust-seized rotor off the hub face. | Required | shop |
| Torque wrench 1/2 in drive, 25-250 ft-lb range Bracket bolts and lug nuts are high-torque and must be set correctly. | Required | shop |
| Torque wrench (small) 3/8 in drive, 10-80 ft-lb Accurate setting of the lower-torque caliper guide pin bolts. | Recommended | shop |
| Wire brush Steel, plus a hub cleaning disc if available Cleans rust off the hub mating face so the new rotor sits flat. | Recommended | shop |
| Impact wrench 1/2 in drive, 500+ ft-lb nut-busting Makes the 21 mm bracket bolts and lug nuts far easier. | Recommended | shop |
| Wheel chocks Keeps the truck from rolling with the front wheels off. | Safety | shop |

| Anti-seize (thin coat) Nickel or copper A light film on the hub face stops the next rotor from rust-welding on. | Consumables | shop |
| Front brake pad set Ceramic or semi-metallic, K2XX 1500 front The wear item being replaced; includes new abutment hardware on most sets. | Parts | shop |
| Front rotors 330 mm (13 in) on most 1500s; verify diameter before ordering Replaced in pairs with the pads. | Parts | shop |
| DOT 3 brake fluid GM-approved DOT 3 Top off the reservoir if fluid level drops or you crack a bleeder. | Consumables | shop |
Brake hardware and tool sizes are the same across the 4.3 V6, 5.3 L83 and 6.2 L86 - the engine does not change the front brake job. What matters is the brake/trailering package and wheel size: most 1500s use a 330 mm front rotor, but some heavy-duty/Max Trailering builds and 2WD/4WD variations can differ, so measure the old rotor. Lug nuts are 22 mm across the generation.
| Caliper bracket (mounting) bolt to steering knuckle | approx. 129 ft-lb (175 Nm) - verify in the service manual for your year |
| Caliper guide pin bolts | approx. 27-30 ft-lb (37-40 Nm) - verify in the service manual |
| Wheel lug nuts | 140 ft-lb (190 Nm) |
| Brake hose banjo bolt (if caliper removed) | verify in the service manual |
Sizes here (22 mm lugs, 18 mm guide pin bolts, 21 mm bracket bolts) match the common K2XX 1500 front brake setup, but bolt heads can vary slightly by year and brake package, so test-fit sockets and confirm the bracket bolt torque in a service manual for your exact year.
The caliper guide pin bolts that hold the caliper to the bracket are typically 18 mm, and the two bracket bolts that go into the steering knuckle are 21 mm. Use 6-point sockets, since the bracket bolts are torqued around 130 ft-lb.
140 ft-lb (190 Nm) with a 22 mm socket, tightened in a star pattern with the truck's weight on the ground. Re-check after about 100 miles.
No. For a pads-only job you only remove the two 18 mm guide pin bolts and slide the caliper off. The 21 mm bracket bolts only come out when you are replacing the rotor.
Corrosion between the rotor hat and the hub face welds them together, especially in salt states. Hit the rotor face between the wheel studs with a dead blow hammer, spray penetrating oil around the center bore, and work around the rotor rather than hammering one spot.
