If your looking to upgrade your 3.5 to R/T brakes, here is a little walk through on what you will need and a small how to.

Estimated time to complete: 3 hours

Parts required:
R/T rotors (Front & Rear)
R/T Calipers (Front & Rear)
R/T Caliper Hangers (or mounts, depending on who you talk to)
R/T Brake Pads (Front & Rear)
R/T Brake lines (Front only, current rear lines can be used)
Brake Fluid

Tools Required:
10mm socket
13mm socket
15mm socket
19mm socket
6” Cresent Wrench
8” Cresent Wrench
Pliers
Brake Bleeder kit ($4.99 at Harbor Freight)


For my upgrade, I have gone with Stock R/T calipers with R1 Concepts Premium Cross-Drilled & Slotted rotors, with Posi Quiet (Ceramic) pads.



1 – Place the car on jackstands and remove the wheels.


2 – Place each corners parts in the respective area. ( I like to have my parts laid out so they are within reaching distance when I am sitting on the floor).

FRONT

3 – Using your 15mm socket and 6” cresent, remove caliper.

4 – Using your 19mm socket, remove caliper hanger.

5 – Remove rotor (there may be 2 clips on the lugs, remove them and the rotor will just pull off).

6 – Using your 10mm socket, remove the bracket on the back side of the “knuckle” that is attached to the brake line.

7 – Attach new brake line to the new caliper.

8 – Using your 6” cresent, unhook the brake line from the metal tube.

9 – Remove clip and pull brake line from the mounting bracket.

10 – Place the new brake line into the bracket and secure with clip.

11 – Attach new brake line.

12 – Attach the bracket to the back side of the knuckle.

12 – Place new rotor onto the hub and secure with 2 lug nuts (Unless you decide you want to replace the 2 clips, I didn’t).

13 – Mount the new hanger (19mm socket).

14 – install brake pads.

15 – Mount new calipers (15mm socket and 6” cresent).




REAR

1 – Using your 15mm socket and 6” cresent, remove caliper.

2 – Using your 19mm socket, remove caliper hanger.

3 – Remove the rotor (make sure the emergency brake is disengaged).

4 – Using your 10mm socket, remove the brake line from the old caliper.

5 – Using your 10mm socket, attach brake line to the new caliper.

6 – Place new rotor onto the hub and secure with 2 lug nuts.

7 - Mount the new hanger (19mm socket).

8 - install brake pads.

9 - Mount new calipers (15mm socket and 6” cresent).



Once you have installed the new brakes, you will need to bleed them. I used this walkthrough from MattRobertson off of LXForums.

Very nice write up. Is that for the RWD or AWD? Or am I just not paying attention. The sun has fried whats left of my brain cells.

good job greg, but the only thing i see that has me concerned with is that if you put rt brakes on the sxt dont you need to up the rim size to a minimum of 18" to take the big brakes. is this true

True! You can't use the R/T brakes on 17" wheels.
