Description

This OE specification component provides reliable and consistent brake actuation, contributing to enhanced safety and durability for the braking system. It ensures precise brake force application and helps to maintain stopping power.

Key Features & Benefits

This little piece is actually pretty simple, but important. It's basically a lever that pushes the brake shoes outward against the brake drum when you hit the brakes. It takes the force from the wheel cylinder and multiplies it, making sure those shoes make good, solid contact. It also pulls the shoes back in a bit when you let off the brakes, creating a little bit of clearance. It's part of your drum brake system, specifically. You'll find one at each wheel that uses drum brakes. It works with the wheel cylinder and the brake shoes – they all have to work together for your brakes to stop the vehicle. Think of it as a key part of the mechanical linkage that actually makes the brakes work.

Symptoms, Risks & Replacements

If this thing fails, you lose braking power on that wheel, plain and simple. It might start subtly – maybe a longer stopping distance, a pulling sensation when you brake. You’ll notice if it gets really bad, like the brakes dragging or feeling really soft. It’s a safety item, for sure. It’s not something you want to put off fixing. We can get these pretty easily, you can even find a good selection at places like Fixparts Online, but more importantly, getting it done right ensures you’re safe on the road.
