91 B2600i Brakes
 

Hello All, new to the forum and Mazda pickups. Having some issues with brake pedal still going all the way to the floor to stop even after bleeding brakes 6 times. Changed the master cylinder and bench bleed that also. Could the ABS Hydraulic Assembly need to be replaced?
Any help is greatly appreciated!!

Usually, ABS is not involved with brake issues like this, if you bled correctly. Did you match up the adjustment of the power booster in case the depth of the new master cylinder was different than the existing one?

I suggest to post your question at MazdaTrucking.com, more expertise there. You also should be able to find a link to the electronic version of the factory service manual there.

thanks Cusser, I did not check that but will this weekend. Appreciate that!
