1. Check for air in the brake hydraulic system. Inspect the brake hydraulic seals, fluid lines and related components for fluid leaks. Remove the air from the brake system by bleeding the brakes. Be sure to use fresh brake fluid that meets the manufacturer’s recommended standards.
2. Check for an internally restricted flexible brake hydraulic hose. Replace the hose and flush the brake system.
3. Check for a seizing brake hydraulic component such as a brake caliper. Check the caliper piston for surface damage such as rust, and measure for out-of-round wear and caliper-to-piston clearance. Overhaul or replace failed parts and flush the brake system.
4. Check the vehicle’s alignment and inspect for suspension wear. Replace worn bushings, ball joints and set alignment to the manufacturer’s specifications.
5. If the brake system uses drum brakes front or rear, check the brake adjustment. Inspect for seized adjusters and clean or replace, then properly adjust.
