Brake proportioning valve

[deeselfitter]

Popped a brake line just a bit ago, replaced the line and have had a Brake warning light on the dash ever since. Does my 2006 have a brake proportioning valve and can I re -centre the “shuttle” to get that light out on the dash. All brakes have been bled and re -bled and they seem to be working fine. It’ll soon be fifth wheel towing season again and just want to get this right. TOA for any suggestions.

No it doesn't, it's all within the ABS unit electronically made.
Have dealer read the codes, it will tell where your problem lays.

I guess you didn't disturb the the brake fluid level sensor.

I’m not really sure , is there any way I can tell just by looking at the master cylinder or something

NO need for a proportioning valve with the ABS system.

The sensor is at the bottom of the reservoir, make sure it is fully plugged in and seated in the reservoir.
That is about the only thing mechanical that can light up the dash light, everything else is electronic and needs to be diagnosed accordingly.

Ok, thanks very much.

Doesn't the AlfaOBD scanner read the ABS System?

This thread got me to inspect my brakes and glad I did:

• missing a caliper pin on passenger front
• torn rubber boot on driver rear
• leak at the brake line fitting on the driver rear caliper

When ordering the parts I found the rear hard lines with the small rubber hoses so ordered them as well. I had already replaced both front and the rear center brake lines with new stainless lines but was told I could not replace the small hoses at the rear calipers without special tools and skills. The original small rubber lines don't look too bad but will swap them out and keep the originals as spares.

FYI, living in Las Vegas my truck has no issues with rust but I have learned that does not mean that rubber parts don't degrade. I was driving my truck into a roundabout when I had to brake for a car entering from my left when the brake pedal went to the floor. Fortunately, I was able to take evasive action to avoid a collision. I limped home and upon inspection the passenger front brake line had burst. Lesson learned. Don't wait 17 years to change those brake lines that look fine from the outside.

As always thanks for all the great information.

Don't know if Alfa works on an 06.

Check your parking brake pedal switch.
