Chase Bays Brake Line Relocation – BMW E46 for BBE

The Chase Bays Brake Line Relocation for BMW E46 with Brake Booster Eliminator (BBE) is designed for enthusiasts who want to eliminate engine bay clutter and improve braking performance by;

• Relocating the brake lines in a much more practical way. (aka Brake Line Tuck or Tucked Brake Lines)
• Replacing the factory proportioning valve / block with our Adjustable Bias Valve.
• Deleting ABS
• Compensating for the different outlets of our Brake Booster Eliminator

The OEM brake hard lines are relocated and replaced and with -3AN stainless steel braided, Teflon PTFE lined, black PVC coated lines. We use the best components in the industry and we pressure test every line we assemble. We guarantee a leak free start up if this product is installed correctly.

This kit keeps all the lines in the engine bay and mounts the Adjustable Bias Valve to the lower master cylinder bolt. We have designed the lines to route in the best path possible. Low on the firewall, below steering column, under frame rail…however we find is the best look while remaining easy to install. Plus, of course, a safe distance from high heat and/or moving objects. The driver to passenger line is installed low on the firewall just above the transmission and will clamp onto existing studs on the firewall.

The clevis will require modifying. You will cut the factory hole type clevis off the E46 brake booster and weld it onto a provided coupler.

The front to rear line is adapted in a unique but necessary way. The factory ABS system is eliminated and there are 2 hard lines that run to the rear of the chassis. To adapt the rear lines to AN, we supply “tube nut” and “tube sleeve” adapters. The factory hard lines are cut, reamed, and the supplied tube nut and tube sleeve are slid onto the hard lines. The hard lines are then flared to 37º degrees using a PROPER 37º FLARE TOOL (link below). Then our clever supplied “F Fitting” will thread into the 2 tube nut and sleeve adapters to make 2 lines into 1, which will then run to the Bias Valve OUT section.

Legend:
OEMC – Original Equipment (or Stock) Master Cylinder
BBE – Brake Booster Eliminator
PTFE – Polyetratluoroethylene aka Teflon
Proportioning Valve & Bias Valve – The component that alters the difference in front and rear pressure. In most cases, the front needs more. Almost all of our Brake Line Relocations include an Adjustable Bias Valve.
ABS – Anti-Lock Brake System. Sometimes needed, sometimes not. How you determine this is up to you but if you have any questions we can provide insight.
