    As you face the BPMV you have the 5 holes
    top 3 to outputs(brakes) and bottom 2 inputs(master)
    Upper Left supplies Left Front brake
    Upper Middle supplies Right Front brake
    Upper Right supplies Rear brake only one that turns and goes directly to rear.
    Lower Left supplies Master Cylinder Secondary/Front Input
    Lower Right supplies Master Cylinder Primary/Front Input

Straus, the brake lines all have different size threads and can only be screwed into the correct ports. How could you screw this up? And how could you call my answer vauge on the wheel bearing diagnosis? Its the only thing that would change with the vehicle weight shift from side to side. Also no Gm 4x4 of this size has a "transaxle". They have a: Transmission,transfer case, and a front and rear differential. No transaxle unit here! You should not be able to give advice here, you have no idea what you are doing or talking about. I have to refix many cars at my work because people like you think you know how to work on cars.

What is a abs modular on a Escalade Cadillac?


Jesse, The module will not stop fluid to rear brakes, a bad master cylinder will,leaking lines, air in brake system, faulty metering block if equipped, collapsed flex lines or pinched brake line faulty caliper or brake cylinders,etc. will cause the possible feeling of no rear brakes.
(ABS Module components) the ABS speed sensors and the ABS control module . When the brake is applied, the ABS control module reads the speed data from the speed sensor and sends the correct pressure to each wheel to prevent any wheel lock up, eg. sliding/skidding Links below have more info.

Probably a really simple question, but on a Mercury Mystique 1997 (manufactured 1996) brake master cylinder (with ABS), which port, front or rear, leads to the front wheel section of the ABS module?


Off the master cylinder. The front tube controls the rear brakes. And the back one controls the front brakes. Just a note. I don't know which year they started doing this, but, the front right brake goes/ties in to the left rear brakes. left front to right rear. This set up runs off the ABS module to the brakes.

Abs brake system


Best case scenario bad vacuum pressure to the brake booster. Worst case bad abs control module or valve body/motor the abs system works by add and removing hydraulic pressure through valves and electric motor. Try using block off plugs at the master cylinder( remove lines plug outlets at master cylinder) check if brake pedal position and pressure is good(if there is no change problem is master cylinder or brake booster/ vacuum) if plugging at master cylinder solved issue repeat procedure at abs valve body after reinstalling lines from master cylinder if your problem returns your issue is in the abs valve body if plugging at the abs solves problem reconnect at the valve body bleed each line one by one testing between each line until you find the problem

Brake line diagram


I have been in the business for 35 years and have never seen a "brake line diagram". You easiest way to figure out which one goes to the right front would be to start at the right front caliper and follow it to the hydraulic control module.
