Begin by collecting all the parts:
LS400 EBC greenstuff

'EARLS' Brake Lines 12"/Fittings/adapters:

-- You have the option to choose whatever brands fits your preferences, this is what i have used and what i recommend. however there are many other very good brands for a variety of purposes and price points. this DIY will work for all brands! --
-- Also, i have chosen to use aftermarket SS braided lines and all new fittings. owever, stock lines/fittings will work with the LS400 calipers.
-breaker bar, or air
-sockets: 14, 17 (deep or small extension)
-allen socket: 10
-wrenches: 10, 13, 15, 18,
(may differ depending on the lines and hard ware you use)
-a press: decent sized hammer and deep socket works too, etc...
-coilover wrenches (optional)
-jack and jack stands
Once your car is up on the lift OR
the front end is jacked up, on stands, and wheels are off...LET'S BEGIN!
Using Stock lines:
- remove the banjo bolt from the stock caliper lines on the caliper only.
- and position it out of your way during the install
Using aftermarket lines:
- Disconnect brake line from hard line using the 10 wrench, dont strip it
, it may be a tad hard to break loose.
- pull the clip that is holding the line in position
- you can leave the other end of the line (the banjo bolt/fitting) attached to the caliper
Remove stock caliper by removing the two 17 bolts that hold it on from behind.
Remove stock rotor using either a rubber mallet or threading a bolt into the small hole near the center of the rotor to break the rotor loose, if it does not just pull right off.
RCA spacer install
Remove the two 17 bolts on the bottom behind the hub that are facing upward, where we will install the FIGS spacer!
with both bolts out, insert spacer...it will only go in one way. and reassemble using the longer bolts supplied by FIGS with the 10 allen socket:
Fully reassembled and re-tightened. Torque to 90 ft/lbs.
The spacer will also lower the front of the vehicle 1" so remember to raise your coilovers to compensate for the difference. this may be a good time to do that. (this may not apply to you if you do not have an adjustable suspension set up)
Cut back dust shield, top and bottom, to clear the rotor. File edges (optional):
DUST SHIELD FINISHED:
Place rotor on hub, secure with two lug nuts, and check for any rubbing. you may have to bend in or lightly hammer out the small divit in the center on the bottom of the dust shield and bend back the edges/corners of the dust shield using a pair of pliers for additional clearance. once all is clear, remove rotor.
Install the FIGS Caliper Adapters into the calipers. these are tapered and will only go in one way! however, they must be installed so that the holes are on the outside/farthest apart, and pressed in.
Install caliper with the two 17 bolts and 17 socket and ratchet to double check clearance and fitment, then remove.
Install the adapter onto the hard line using the 10 and 15, then secure with pin. install banjo fitting and tighten onto caliper using the 14 socket.
Install rotor and temporarily secure with 2 lug nuts. install caliper using the two 17 bolts and 17 socket and ratchet. tighten until snug, once again torque specs unknown, however they are not critical. just make sure they are tight!
Install brake line onto the banjo fitting with the 13 wrench, and then to the hard line adapter using the 13 and 15 wrench.
AND YOU ARE DONE WITH THE LS400 CALIPER SWAP!
Remember you still must bleed your brakes, reinstall your wheels, and lower your car from the jacks before you can hit the road! also follow the guidelines for proper rotor/pad break in.
