If you can only stop your truck by pumping the brake peddle three to four times, does that indicate that the ASB hydraulic valve assembly is not working? Just had all the brake parts that were rubber replaced, front brake disc, seals, front rotor,brake hoses,wheel cylinders, master, comb vavle, rear hoses and my truck still has to have the brake peddel pumped 3 to 4 times before I can stop it. HELP PLEASE for your advise.

1990 Mazda B2200 Question: Does the ABS hydraulic Valve Assembly have anything to with stopping your truck?
do you have a good pedal when 1st depressed or does it take 2 or 3 pumps to get the pedal firm? if it takes several pumps to get pedal firm,tjat indicates air in the system. you need to bleed the entire brake system of air
