## Overview

The GM Genuine Parts 172-2777 Front Driver Side Disc Brake Caliper Assembly is a precision-engineered hydraulic component designed to replace your GM vehicle’s original caliper.

## Description

ACDelco GM Original Equipment Disc Brake Calipers are hydraulic components mounted over the brake rotor. The caliper acts as a clamp to press the brake pads against the brake rotor when the brakes are applied. These original equipment disc brake calipers have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Review: Great caliper that has a bunch of different vehicle applications. Big brake brembos at a reasonable price. I just wish they could remove the Cadillac and powder coat them in red.
Review: Like the previous review for the C5 owner, I was curious about this for a C4 since the calipers are so cheap (barely any more expensive than the adapter brackets to do the C5 upgrade which is barely better than the C4 J55 brakes) and I was having clearance issues with the C5 one. Because of where they mount in relation to the knuckle vs on a C5/C6 I had to do minor filing if the inside of the rotor hat, they needed to be spaced out from the knuckle to center on the rotor (I used YFS CDC14060-8 Grade 12.9 socket cap bolts) and wheel clearance will be extra particular (they fit my OEM C5 Z06 18x10.5 58mm offset wheels), and instead of the C6 Z06 14" rotors I had to use the Powerstop C6 Z51 13.4" brake rotors (which aligns near perfectly with the brake pad area). All told a pretty good upgrade in style/feel that's barely any heavier than the stock J55 setup and actually about a pound lighter per side than the C5 calipers with the C5 adapter bracket and C6 J55 rotors.

## Questions & Answers

**Q: Why do brakes need to be replaced in the first place?**
A: Friction material on the brake pad contacts the rotors to slow the vehicle. In time, that material wears away and the pads must be replaced. Sometimes the rotors and calipers must also be replaced.

**Q: What are the calipers and why do they need to be replaced?**
A: Components associated with calipers, including seals, pistons, mounting hardware and more, can wear and degrade braking performance. This may result in the need for the calipers’ replacement.

**Q: What are the signs of a bad brake caliper?**
A: Symptoms can include pulling to one side when braking or a soft/spongy feel in the brake pedal. A stuck caliper piston can also create “dragging,” with the pads continuing to rub on the rotor.

**Q: Is a brake fluid leak due to the caliper?**
A: Very possibly. A failed seal or other issue with the caliper can result in a brake fluid leak. There are other reasons brake fluid may be leaking, including a damaged brake hose. The leak should be inspected immediately.

**Q: What about vibrations or shaking in the steering wheel?**
A: If the brakes are very worn or the rotors have uneven wear, there can be a significant vibration or shaking in the steering wheel when braking. This could be the result of a sticking caliper that is causing excessive and/or uneven brake wear.

*by S***N on 8 August 2022*

This caliper, matched to its twin on the other side, both mount to the C5 knuckles perfectly. Matched with some C6 Z06 rotors, throw alittle paint on them and boom you have a perfect budge OE brembo kit. Supper happy with the results.
