I drive a 2002 Land Rover Discovery II. I have had the brake lines bled twice and cannot get rid of the spongy pedal associated with air in the brake lines. If the pedal is pumped one time the brakes return to normal. There are no visible signs of a leak. Can air be trapped elsewhere besides the lines going to the calipers? Any suggestions? Already Tried: Bleeding the brake lines at the calipers.
Answer:
You need to Bleed the system at the Bleeders, not just at the lines going into the caliper.
1) Brake pedal feels spongy or has excessive travel
Check the brake fluid level and condition. If the fluid is contaminated or has not been flushed every two years, clean the master cylinder reservoir, and bleed and flush the brakes using fresh brake fluid that meets the manufacturer's recommended standards.

2) Check for a weak or damaged flexible brake hydraulic hose. Replace the hose and flush the brake system.
3) 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.
