I recently bought a 2008 RT after having owned an LT for 5 years, I performed the brake flush on the LT with the help of John Zeiler's DVD but was wondering about the 08 RT flush. I know there is no servo pump since I can't hear anything activate on startup and am wondering if its just a simple "press and pump" flush procedure or is it still made up of open and closed circuit fluid systems like the LT due to the ABS.

Does anyone have a blake flush procedure for a 2008 RT?

thanks

Just a normal flush is fine. There was some talk that you could then go and brake hard to activate the abs and circulate the fluid from the abs unit, but I don't know that you don't do that with regular bleeding and braking.
The only procedure the RepROM gives is on the servo unit.

Nothing like the LT servo brakes.
You can do the fill, pump, bleed or use a vacuum bleeder, yes that is an approved method per BMW for this system but they still want you to finish with a pump and bleed.

Like the LT, retract the pads into the caliper and shim/block them before you bleed the system.
Start your bleed at the master cylinder bleed nipple and after you bleed the calipers finish by bleeding at the mater cylinder a 2nd time (front only).
When doing the front start with the LF then go to the RF.

Rear is straight forward.

Without the whizzie brake, the 08 bleeds like your car- nothing unusual about it in any way.
