Tech Tip: Why Staggered Pistons Are Important for Brake Calipers
If you're a car enthusiast or mechanic, you may have heard of staggered or tapered pistons in calipers. But why are they important? In this tech tip, we'll explain the science behind them and why they can improve the efficiency of your braking system
To understand why we use staggered or tapered pistons, we need to look at how brake pads wear over time. As the pad is grabbed by the rotor, the leading edge of the brake pad digs in and grabs more bite, causing it to wear more than the trailing edge. With a standard set of caliper pistons or even a single piston, this can lead to uneven wear and decreased efficiency.
This is where staggered or tapered pistons come in. By using a large piston on one side and a smaller piston on the other, we can push less on the leading edge and more on the trailing edge, promoting even wear and increasing the overall efficiency of the braking system.
But why is this important? As your brake pads wear at an angle, the piston is pushed at an angle, which can cause it to bind in the bores and create more drag, wear, and heat. By using tapered pistons, we can prevent this from happening and keep our braking system running smoothly.
So, what's the takeaway? Replace your brake pads regularly to keep them nice and square, and consider using staggered or tapered pistons in your calipers to promote even wear and increase the efficiency of your braking system. With this simple upgrade, you'll be able to brake with confidence and precision.
