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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ OEM made in China *by C***K on January 1, 2025* Good quality and has worked well so far. This was a General Motors replacement part in a GM Delco box. Inside it says made in China. I probably won’t buy again. Will buy American made if I can find one. ### ⭐⭐⭐⭐⭐ Great *by M***S on April 29, 2025* I like how it fit pretty well ### ⭐⭐⭐⭐⭐ Perfect Factory Replacement *by D***L on May 13, 2024* Install was easy, I originally replaced my hydro pump and was still getting fluid contamination. Had to drain my brakes a few times on couple long trip. Finally replace the brake master cylinder and it fixed the problem. Pre-bleeding the master cylinder was the key to eliminating air in the lines. ## Frequently Bought Together - ACDelco Professional 18M2426 Brake Master Cylinder Assembly - General Motors 22872387 Power Brake Booster Gasket - ACDelco GM Genuine Parts 178-1036 Power Brake Booster Assembly --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/19241239-gold-18m2426-19288627-brake-master-cylinder-assembly](https://www.desertcart.co.za/products/19241239-gold-18m2426-19288627-brake-master-cylinder-assembly) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-23*
