[W126 Coupe] Brakes and air

[Gerry Van Zandt]

Nope, that line is (oops ... WAS ... see below) well over $100.  I just replaced it this past spring when I did my top-end rebuild.  I unscrewed the ends at the manifold and the brake booster, and the line broke in two in my hands as I pulled it through the inner firewall.  The vacuum piece just disintegrated.

PLEASE READ & UNDERSTAND THIS:  If this line has never been replaced on your car, you are living on EXTREMELY borrowed time.  Spend the money and replace it.  It sits right above the transverse pipe that connects the two exhaust manifolds on US 560 and 420 cars, so it gets heat-baked over the years.  It's a 10-minute job to replace this hose.

Part number for the US 420/560 is:  126 430 28 29.  List price is currently $62 from MB, and you can get it from parts.com for $42 + shipping.

This is a GREAT deal!  The price has just been drastically reduced on this hose.  This spring when I replaced mine, the MB list price was $117, and I felt lucky to get it from parts.com for $80.50.

You can see this black hose and white check valve on my engine (before I replaced them) in the upper right corner of this photo from my rebuild:
