Fixing Caliper Issues on Your 2020 Chevrolet Corvette

How to Fix Caliper Issues

This guide helps 2020 Chevrolet Corvette owners address caliper issues. We'll cover common symptoms, likely causes, diagnostic steps, and fixes based on owner experiences and parts mentioned in their discussions.

Symptoms

Owners have reported several symptoms related to caliper problems, including rust, coolant leaks, drips, eyeballs, and overspray. Some owners have mentioned these issues in conjunction with the rear inner fender extensions.

Most Likely Cause

Based on owner discussions, the primary cause for caliper problems appears to be with the barrels themselves. Corrosion or damage to the caliper barrels can lead to leaks and other performance issues.

How to Diagnose

1. Visual Inspection: Carefully inspect the calipers for signs of rust, especially around the barrels. Look for any visible leaks or drips of brake fluid.

2. Check Fittings and Hoses: Inspect the fittings and hoses connected to the calipers. Look for cracks, leaks, or damage. Pay attention to the areas where hoses connect to the calipers.

3. Examine Rear Inner Fender Extensions: Check the rear inner fender extensions, as some owners have mentioned these in relation to caliper issues. Look for any signs of overspray or damage that might indicate a problem.

Step-by-Step Fix

1. Gather Parts and Tools: Before starting any repair, ensure you have the necessary parts, including replacement calipers (if needed), fittings, hoses (potentially Stoptech lines), and any required tools.

2. Replace Damaged Calipers: If the caliper barrels are corroded or damaged beyond repair, replacing the entire caliper is often the best solution. Follow the manufacturer's instructions for proper installation and bleeding of the brake system.

3. Replace Fittings and Hoses: If fittings or hoses show signs of damage or leaks, replace them with new components. Ensure you use the correct fittings and torque them to the specified values. Consider upgrading to Stoptech lines for improved performance and durability.

4. Inspect and Repair Rear Inner Fender Extensions: If you find any overspray or damage on the rear inner fender extensions, clean and repair them as needed. This can help prevent future issues and maintain the overall appearance of your Corvette.

5. Bleed the Brakes: After replacing any components in the brake system, it's crucial to bleed the brakes to remove any air and ensure proper brake function. Follow the recommended bleeding procedure for your vehicle.

Real Owner Costs

The cost of fixing caliper issues can vary depending on the extent of the damage and the parts that need to be replaced. Replacement calipers can range from $200 to $500 each, depending on the brand and quality. Fittings and hoses can cost anywhere from $50 to $200. Labor costs will vary depending on the shop and the complexity of the repair.

What Owners Say

Real experiences from CHEVROLET owners:

Owner Experiences

"I also used the factory style pads from Raybestos (padlets) so basically I reduced my pad contact quite a bit. I'm looking at the Hawk pads that are full size so the contact area should increase to what it was.the Appreciate the input as I wasn't even looking this direction." — Kubs (source)

"From looking online I'm seeing the Z6 rear piston at 4@30mm . I also used the factory style pads from Raybestos (padlets) so basically I reduced my pad contact quite a bit." — Kubs (source)

"But as I noted in a recent post on my build thread the barrier to entry cost for those kits are the 2-piece rotors. Without any of those in the mix it doesn't appear to be a worthwhile move." — Tusc (source)

Prevention

• Regular Inspections: Regularly inspect your brake system, including the calipers, fittings, and hoses, for any signs of wear or damage.

• Proper Maintenance: Follow the manufacturer's recommended maintenance schedule for your brake system, including fluid flushes and inspections.

• Use Quality Parts: When replacing brake components, use high-quality parts from reputable brands to ensure optimal performance and durability.

• Address Issues Promptly: If you notice any symptoms of caliper problems, such as leaks or unusual brake performance, address them promptly to prevent further damage.
