Wabco 12303003 Dished Plate Spring Set

Description

This is a set of Dished Plate Springs designed for brake caliper applications within braking systems. These springs are crucial components for ensuring proper brake function and performance. Manufactured by Wabco with MPN 12303003, this set provides a precise and reliable solution for brake control systems. The dimensions of each spring are 48 x 144 x 79 mm. These springs are engineered to meet OE specifications, delivering enhanced durability, consistent performance, and improved brake responsiveness.

Key Features & Benefits

These little springs actually have a surprisingly important job. They sit inside your brake caliper, underneath those brake pads. Their main function is to keep constant pressure on the caliper pistons, pushing them slightly outward. They also help the pads retract a small amount when you let off the brake pedal. It’s a really subtle movement, but crucial for consistent brake performance. They basically counteract the tendency of the pistons to stick a little. Think of these springs as being part of the system that keeps your brakes responsive. When you hit the pedal, it activates the hydraulics, which push the pistons out and clamp the pads onto the rotor. But when you release the pedal, these springs gently pull the pistons back just enough to prevent constant rubbing. They’re working alongside the caliper slide pins to ensure everything moves freely. They’re a small part, but everything in the brake system has to work together.

Symptoms, Risks & Replacements

Honestly, if these springs get weak or break, you’ll notice if you drive long enough. You might experience a spongy brake pedal, or feel like you have to press the pedal further to get the same stopping power. It could also lead to uneven pad wear, or even the pads dragging on the rotors – meaning they’re staying engaged even when you aren’t braking. That creates heat, wears down parts faster, and reduces fuel economy. They're like a shield against sticking and dragging. You can find a good set of these, like the ones we carry at Fixparts Online, pretty easily. Replacing them is a good preventative maintenance item, especially if you're already doing other brake work.
