All of our inInterior Brake Line Relocations require the use of our Single Piston Brake Booster Eliminator. 

Before we get into this install guide, MotorTrend did an excellent write up about this kit. It can be applied to all forms of these kits based on the pictures/explanations. 

Check that out here! 


Single Piston Brake Booster Eliminator Install:

  • Disconnect the brake lines at the master cylinder/abs module and remove from the engine bay.
  • Install the BBE through the holes in the firewall where the OE Master Cylinder/Brake Booster was located and secure it using the 4x M8 nuts supplied with the BBE.
  • Adjust the clevis on the BBE so that the pin can slide through it and the brake pedal without having to manipulate either to get the holes to line up.
  • Tighten the 5/16 x 24 nut on the Master Cylinder rod against the clevis to keep it from moving.
Bench Bleeding: 
  • We recommend bench bleeding the BBE Master Cylinder prior to connecting all lines. This is easiest done by securing one of the brake lines in your Brake Line Relocation Kit to the 3AN banjo adapter on the Master Cylinder and putting the other end of the line in the Brake Reservoir.
  • Fill up the reservoir with brake fluid and begin pumping the pedal, making sure that the free end of the Brake Line is completely submerged in brake fluid.
  • Continue pumping the pedal for a few minutes until you can not see any bubbles coming out of the Brake Line in the reservoir. Once there are no more bubbles you're good to go!

Next, you will install the bulkhead fitting and hardline to bring the lines to the interior.

  • Thread the hardline onto the outlet banjo adapter of the BBE facing down. Rotate the hardline to the firewall so that the tube nut/sleeve is in the small flat area of firewall next to the BBE. The hardline might need to be very slightly adjusted to sit exactly where you need it to in order to line up with the firewall. However, DO NOT EXCESSIVELY BEND THE HARDLINE - this can kink the line which prevents proper braking, or even crack the material if done improperly. 
  • Using a marker or other marking tool, mark the center point of where the hardline goes into the firewall. Use a drill with a 3/8" or 10mm drill bit to make the hole for the bulkhead fitting. 
  • Install the bulkhead T fitting into the hole from the interior side and accompanying adapter to the end of the fitting, then re-install the bulkhead nut on the engine bay side.
  • Tighten the bulkhead nut to secure it through the firewall, then install the hardline to the bulkhead from the engine bay side. Tighten the hardline at both ends. 

 

inInterior Brake Line Relocation Installations

LHD 94-01 Integra & 92-95 Honda Civic with BBE inInterior (CB-H-9201BBEINT)

1. First, you want to lay all of the lines out on the floor so you can get an idea of what goes where. This is one of the largest kits we make, and we completely understand how it can be confusing/daunting to install. The kit will install front to back starting at the bulkhead T & T with female portion that should already be installed to the firewall at this point. 

2. Next, we will route the lines to the front fenderwell areas. You will use the longest line without a Chase Bays Label and the one that is about a foot, both are 90 to straight fitting end lines, and install both of them to the bulkhead T & T fitting adapters in the firewall. The shorter line will use the straight end on the T to go to the area behind the front driver side wheel well, and the longer line will use the 90 end on the T to go to the area behind the front passenger wheel well.

3. Then, you will need to install the shortest pair of 90 degree male M10 to straight 3AN lines to the Fenderwell Line connections in the front fenderwells. These lines will need to be installed to help locate the spots to drill for bulkheads in the next step. 

4. Now you will need to carefully mark and drill a 3/8" or 10mm hole the areas that allow the 90 degree bulkheads to pass through to the wheel wells. You can drill from either side, just make sure where you drill lines up with the correct area on the opposite side.

5. Now that the holes are drilled, install the bulkheads from the interior side to the wheel wells. Attach the bulkhead nuts from the wheel well side, and use the previously installed lines to connect the wheel well side to the interior side of your braking system. 

6. Move back into the interior of the car with the longest line in the kit with the Chase Bays logo. Install the 90 degree end of this line to the initial bulkhead T, and the logo end to the inlet of the Bias Valve. Route the line through your interior behind the dashboard to get the Bias Valve in the location you desire. We shall mount this Bias Valve at the end of the install to ensure there are no hang-ups while fitting the rest of the kit. 

7. The 4 foot line with straights on both ends will attach to the outlet of the Bias Valve and route to the rear of the car. Attach the T fitting to that line, and both of the straight ends of the 2 foot lines to that fitting. These lines can be tucked under the rear interior/carpet/seats at the end of the install once you confirm all of the connections are tightened. 

8. Then, you will need to install the shortest pair of straight male M10 to 45 degree 3AN lines to the Fenderwell Line connections in the rear fenderwells. These lines will need to be installed to help locate the spots to drill for bulkheads in the next step. 

9. Once again, you will need to carefully mark and drill a 3/8" or 10mm hole the areas that allow the 90 degree bulkheads to pass through to the rear wheel wells. You can drill from either side, just make sure where you drill lines up with the correct area on the opposite side.

10. Now that the holes are drilled, install the bulkheads from the wheel well side to the interior. Attach the bulkhead nuts from the interior side, and use the previously installed lines to connect the wheel well side to the interior side of your braking system. 

11. This is arguably the most important step. Double check all of your routing, connections, and Bias Valve location. Once you have determined everything looks correct, and the lines are routed as needed, tighten every connection starting from the front firewall to the rear wheel wells in order as they were installed.

Things to look for:

  • Make sure the bulkhead nuts are tightened at all 5 locations before tightening lines to them.
  • All Fenderwell Line connections are tightened and their connections at each caliper. 
  • Bias Valve is mounted in a location that does not interfere with shifter or seats. 
  • Banjo bolt on the front of the BBE is tightened, as well as the hardline connections.

12. Now that everything is connected you will need to bleed each caliper, we suggest doing this with the Bias Valve knob all the way adjusted to give the most flow to the rear calipers. You can use a pressure or vacuum bleeder but, we have gotten the best results by using the two person method having one person pumping the pedal and another bleeding air at the caliper. You will want to start at the caliper furthest away from the master cylinder (passenger rear) and work your way to the closest caliper (driver front).
