## Overview

STP 17921 Synthetic DOT 4 Brake Fluid is a premium 12 fl. oz. synthetic brake fluid engineered to elevate braking performance by increasing the dry boiling point above 270°C, preventing vapor lock, and protecting against corrosion. Compatible with all DOT 4 brake systems, it meets and exceeds key federal and SAE safety standards, ensuring reliable, fade-free braking for modern vehicles.

## Description

As your brake pads wear, the level of brake fluid drops. STP Synthetic Brake Fluid DOT 4 is specially formulated to get optimum performance out of disc or drum brake systems in today's cars and trucks.

Review: My old car brake fluid level is getting low, so decided to add this product in. Before I pour this in, I stepped on break and slowly pushed it down few times.. After settled down a bit, opened and filled up the fluid container. It certainly made breaking more firmly and responsibly. I recommend this product.
