Evo IX Brembo Caliper Rebuild -- Torque specs
Hey everyone.
I'm taking my front and rear Brembo calipers apart to have them powder coated on my Evo IX MR, and I'm looking to find the torque specs for all of the bolts for when I get them back and have to put them all back together. I found several threads on the torque specs for the 2 bolts that mount the caliper to the car, but none of the other dozen or so bolts involved.
More specifically, I am looking for the torque specs for:
The two metal brake line fittings that run between the front and rear sections of the caliper.
The four bolts holding the two caliper halves together.
The two bleeder valves nuts.
The bolt that holds the actual brake line to the caliper.
(For posterity, the mounting bolts for the front and rear are:
Front brake assembly mounting bolt 108 ± 10 N⋅m (80 ± 7 ft-lb)
Rear brake assembly mounting bolt 54 ± 5 N⋅m (40 ± 4 ft-lb))
Since they are aluminum, I don't want to just crank it it tills its tight. I want to do it to spec. So any help would be appreciated.

I haven't split anything apart yet. The powder coating place I've been talking to won't take them unless they are split apart. I spoke to a mechanic friend of mine and he told me the bolts are stretch bolts, and he didn't recommend that I split them either, unless I had replacement bolts as well... Now I have a problem... I have a car with no brakes in my garage, and questionable choices ahead of me...
Can anyone tell me their reasoning to NOT split them aside from the stretch bolt issue that I mentioned? I'd like to make the most educated choice as possible... Especially since now I have a completely useless car.

In all seriousness, I've rebuild about 6 sets of Brembo calipers and powder coated them all. I have NEVER split them. The set that did get pulled apart (not by me) leaked. So do what you want, but I see no point in splitting them. Just find another powder coater.

On a related note to this. What do you do about the brake fluid? Cap the lines some how? Or drain the system and refill/bleed? What about the ABS pump wont it have air in it if the lines just sit open for an extended period of time?
