    What I'm needing to see is a diagram of the brake lines running to the " ABS Block" on the frame. Someone had the bright idea to replace all the brake lines at the same time. Now I'm not getting any fluid to the rear brakes and am unable to bleed the system.

I am assuming this is what your referring too

CLICK HERE

now basically how is functions is this,,

the abs sensor is on the calipers ,,now when you apply brake, the sensor is controlled by the ecu and rapidly grabs and release for a smoothing braking..

now if you suspect that your abs may be giving problems simply remove the abs fuse from he fuse box under the hood. upon removing the cover of the box there is a diagram printed on the inner part of the cover. Removing the abs fuse will disable the abs system,, this will in turn cause the brake to function as would in a normal vehicle. so you can drive safely without the abs system.. Now if the vehicle functions well without the abs enabled and bad with it enabled, more than likely the abs sensor needs replacing..

You didnt give much info on what your problem was except ask for the diagram and i assume thats because the abs is giving you a headace and you needed the diagram t fix it ?? If no and I'm dead wrong, please just add a comment to his POST dont create a new one,,,, and I'll try my best to help you out..

regards

The brake lines run from the master cylinder to each wheel.The brake master cylinder is in the rear of the Sierra's engine compartment, near the driver's seat.Its connected to brake pedal. Raise the truck on jack stands before doing this so be careful.Remove the wheels to reach the brake lines you are replacing.Remove the brake line by disconnecting the connector bolts. While Installing the new brake line, starting from the master cylinder. The new line should be measured and bent to match the original line.The procedure to bleed the brake line:---

First connect the opened bleeder valve on the caliper to a container of brake fluid with a vinyl tube. With help of another person let him press on the brake pedal to remove the air. Top off the master cylinder afterward.

I replaced main brake line on driver side on 2000 1500 Dodge Ram pick up blead all brakes at each caliper no air present. Driven around six hour but abs and brake light still on.


If there is an ABS issue it will turn on the red brake light as well. Were these lights on before the repair? You can try disconnecting the battery to see if the ABS resets. If the lights come back on you will have to have a scan test performed on the ABS system to isolate the problem

Brake line on chevy silverado broken,need diagram to follow line back to box in middle of truck


Brake line diagrams dont exist like wiring diagrams do. If your truck has ABS, that's the ABS controller, and if not it's just the proportioning/metering valve.

1997 ford escort brake line diagram


The LF and RR are in an independent circuit of the RF, LR wheels. The master cylinder already has the lines hooked up in a way that if you trace the lines, you can make your own diagram.

Where is the ABS sensonr located on 1997 Intrepid?


Majority of vehicles have a magnetic pick-up right behind the brake rotor. It picks up this signal from a metal disc with perforation. It has to know how fast or slow it's spinning and sending that data back to the ABS control module. It could also use the disc brake rotor too picking the signal from the top edge (I'm just guessing on that set up although possible). It has two wires coming out from it. Some cars have a brake pad wear sensor that has two wires coming out of the brake pads, so don't confuse this as an ABS pick up. It could also be called a wheel speed sensor.

Leaking brake fluid from rear driver side brake lines,need a diagram of how to replace the lines. 1994 ford taurus 3.o v6.thanks


They don't make diagrams for brake lines. The lines are sold in bulk. You need to measure and duplicate the bends in the orignal lines and cut/flare the lines yourself. You will need a tubing cutter, flare tool and tubing bender.

Brake diagram for 1995 dodge caravan


Could be air in the line..
Could be the caliper..
Could be the break line - the flexable line that runs from the metal line to the caliper..

If you get a Chilton Book for that car - it has how to diagams for breaks, electric - etc.
A good investment..

Rate well ;o)

Brake line diagram


Brake Lines and Hoses
Double-walled steel line is used in the hydraulic lines between the brake master cylinder and the front tube connector, and between the brake master cylinder and the flexible brake hose at the rear wheels.
Double-flared brake lines provide good leak-proof connections.
When replacing hydraulic brake lines, hoses, or connectors, tighten all connections securely. After replacement, bleed the brake system; refer to Section 206-00 .
The wet appearance of the outer cover of the rubber brake hose is referred to as "sweating." This is a normal condition for neoprene rayon braid hose and is not a sign of leakage or cause for replacement of the hose.
