Bleeding your Chrysler’s ABS brakes might seem intimidating without a scan tool, but it’s a manageable task with the right approach. This comprehensive guide will walk you through the process step-by-step, empowering you to tackle this common car maintenance job confidently.
Understanding Your Chrysler ABS Brake System
Before diving into the bleeding process, it’s crucial to understand the basics of your Chrysler’s Anti-lock Braking System (ABS). Unlike traditional braking systems, ABS prevents wheel lockup during hard braking, ensuring optimal vehicle control.

When to Bleed Your Chrysler ABS Brakes
Air in your brake lines can lead to a spongy brake pedal feel and reduced braking efficiency. Here’s when you should consider bleeding your Chrysler’s ABS brakes:
- After opening the brake system: This includes tasks like replacing brake lines, calipers, or the master cylinder.
- Soft or spongy brake pedal: If your brake pedal feels soft or sinks to the floor, it’s a telltale sign of air in the system.
- ABS warning light: A glowing ABS warning light on your dashboard can indicate air in the lines.
Gathering the Necessary Tools
Before you begin, gather these essential tools:
- Brake fluid: Use the DOT 3 or DOT 4 brake fluid specified in your Chrysler’s owner’s manual.
- Clear tubing: A length of clear tubing that fits snugly over the bleeder valve nipple.
- Wrench: A wrench that fits the bleeder valve on your Chrysler’s brake calipers.
- Container: A clear container to collect the old brake fluid.
- Helper: An extra pair of hands to assist with the bleeding process.
- Jack and jack stands: To safely lift and support your vehicle.
Bleeding Chrysler ABS Brakes: A Step-by-Step Guide
Follow these steps meticulously to bleed your Chrysler’s ABS brakes without a scan tool:
-
Prepare Your Vehicle: Park your Chrysler on a level surface, engage the parking brake, and chock the rear wheels for safety.
-
Locate the Master Cylinder: Open the hood and identify the brake master cylinder, typically situated on the driver’s side of the firewall.
-
Clean the Master Cylinder: Remove the cap carefully and use a clean cloth to wipe away any dirt or debris from the reservoir.
-
Fill with Fresh Brake Fluid: Pour fresh brake fluid into the master cylinder reservoir, ensuring it remains above the minimum level throughout the bleeding process.

-
Bleed the Brakes: Starting with the wheel farthest from the master cylinder, follow this sequence: right rear, left rear, right front, left front.
-
Attach Tubing and Open Bleeder Valve: Fit one end of the clear tubing over the bleeder valve nipple on the first brake caliper. Submerge the other end of the tubing in the container partially filled with brake fluid.
-
Depress the Brake Pedal: Instruct your helper to depress the brake pedal firmly and hold it down.
-
Loosen the Bleeder Valve: While the pedal is depressed, use the wrench to loosen the bleeder valve slightly. You’ll observe old brake fluid mixed with air bubbles flowing through the tubing.
-
Tighten the Bleeder Valve: Once the fluid flow becomes consistent and free of bubbles, tighten the bleeder valve.
-
Repeat Steps 6-9: Repeat the process for each wheel, ensuring the master cylinder remains topped off with brake fluid throughout.
-
Double-Check and Test Drive: After bleeding all four wheels, double-check the brake fluid level in the master cylinder and securely tighten the reservoir cap. Start your Chrysler and gently test the brakes in a safe environment.
