Antilock braking systems are even less tolerant of contaminated fluid and air than non-ABS. The ABS hydraulic pump operates at several thousand psi, forcing brake fluid through very small valves. This can whip air and brake fluid into something like the foam on a latte, which makes bleeding difficult.
