Knowing how to bleed ABS brakes is a required skill for proper maintenance-brake fluid should be replaced every two years and after any brake repair. Brake fluid can be compromised by air, water or debris-bleeding the lines replaces the old brake fluid with new, clean fluid.
The Antilock Brake System (ABS) modulator is the device that controls the application of breaking power in an emergency breaking event. This complex unit sits between the master cylinder and the rest of the braking system. ABS modulators have between 8 and 10 valves, making it impossible to effectively bleed these units without the use of specialized equipment.
Bleeding ABS Brakes Safely
If you are repairing or replacing components below the modulator, than standard bleeding technique can be used. Repairs to the modulator or upstream components, however, require a different technique. Here's how to tackle it:
Changing disc brakes gets easier each time you do it. But you can skip to the advanced class just by following a few basic tips.
How do ABS brakes work? They prevent your wheels from locking up at the worst possible time.
