Should Front and Rear Brake Pads Be Replaced Together?
2 Answers
Front and rear brake pads do not need to be replaced together as they have different replacement cycles. Under normal driving conditions, front brake pads typically require replacement every 30,000 to 50,000 kilometers, while rear brake pads can last approximately 60,000 to 100,000 kilometers before needing replacement. Key considerations for brake pad replacement: 1. Always use original equipment manufacturer (OEM) brake pads during replacement to ensure optimal braking performance and minimal wear between the pads and rotors; 2. Special tools must be used to retract the brake caliper pistons during pad replacement; 3. After installing new brake pads, firmly depress the brake pedal several times to eliminate any clearance between the pads and rotors.
After driving for so many years, I've seen quite a few brake issues. The wear rate of front and rear brake pads differs, with the front pads usually wearing out faster because the vehicle's weight shifts forward during braking, placing most of the load on the front. The rear pads may wear half as fast or even slower. So, they don't necessarily need to be replaced together, but regular thickness checks are essential. If the front pads are thin while the rear ones are still thick, replacing just the front pads is fine, but it's best to replace both simultaneously to ensure balanced braking. Otherwise, replacing only one side may cause uneven braking, leading to vibrations or instability while driving, especially in rainy conditions or at high speeds, which poses greater risks. In terms of cost, replacing both at once saves on labor fees, and parts can often be purchased as a bundle. Replacing them separately might mean more trips to the repair shop. Personally, I make it a habit to have a professional inspection every two years—safety first, don't wait until you hear squeaking to take action.
