## Description

GM Genuine Parts Power Brake Boosters are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These boosters connect the brake pedal apply system to the master cylinder. The brake booster is a force multiplier that causes additional force to be applied to the master cylinder for additional braking power. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Review: Amazing upgrade 2005 GMC Sierra - WOW! Amazing, the brakes stop my truck better than the day I drove it off the lot. Perfect fit on my 2005 GMC Sierra 3500. Recommend everyone upgrade their trucks!!! Watch You tube before attempting the change out. I did put one on a second truck. This time the transmission failed to shift. Although instead of drilling the shaft hole out 1mm, I disassembled the brake light switch and readjusted the contact,. One of three contacts in the switch, foreword most one. Now the throw is shorter and fixed the issue without drilling the hole. Just wear safety glasses as there is a spring inside the switch that may pop out and hit you in the face the first time you disassemble it. Seemed a bit overwhelming at first but, it was relatively easy once I got it apart. The brake light switch on the 2011 GM is a bit different than the 03-07 models. Very pleased with the result. I did order a second switch in case I failed, Now that extra sets in the glove box as a trophy reminder of the simple fix it was without drilling.
Review: Great fit and good pedal feel - I installed this on my 03 sierra 2500HD. It fit perfect and the brakes feel so much more responsive than before. Like others have said, you may have to open up the hole on the shift that connects to the brake pedal. At first I did not but did in the end as I was trying to trouble shoot why my truck wouldn't come out of Park after everything was installed. Turns out I had damaged the brake switch when I was removing the 4 nuts under the dash. Be very careful with this switch and remove it fully so it does not get knocked around. Very happy with this product and would have been an easy install if I hadn't damaged the switch. Much cheaper than the direct replacement one too.

## 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’s the squealing sound I hear when braking?**
A: Over time, wear indicators in brake pads may contact the rotors’ surface when braking, resulting in a metallic squealing sound. Vehicles equipped with wear sensors may also provide an alert that minimum brake pad thickness has been reached.

**Q: What if it’s more of a grinding sound?**
A: If all the friction material has been worn away, the metal backing plate of the brake pad will be the material in contact with the rotor during braking. It causes a grinding sound and braking performance is often diminished.

**Q: Why do the brakes seem to pulsate when stopping?**
A: It may be due to worn brake pads, unevenly worn rotors or unevenly worn tires. Have the pulsation diagnosed as soon as possible to avoid the possibility of greater brake system wear or damage.

**Q: What about vibrations or shaking in the steering wheel?**
A: This is more serious than pulsation. If the brakes are very worn or the rotors are unevenly worn, there can be a significant vibration or shaking in the steering wheel when braking. It may mean brake service is needed immediately.
