Hello! I am in the process of prepping my 17’ M2 6MT for an HPDE at Mid-Ohio in a few weeks.

I have 2L Castrol SRF coming to replace OEM Fluid as well as the Motive power bleeder and some other goodies. I am familiar with the flush/bleed.

Am I going to need Ista to flush DSC/ABS? Or will the power bleeder push the fluid out of there? I am just concerned I will not have all the OEM fluid out.

I’ve never actuated the ABS when doing brake fluid change and never had any issues.

I've flushed my fluid multiple times without using ista, no issues. Worst case when you go bed in the pads or just want to do a few panic stops you should trigger abs. Go back home and re-bleed the system.

Hi there - you running at the NOR PCA event on May 5-7? If so I’ll be there as well! Ironically, I just put in some SRF for my M2. Did not use ISTA. Just power bled the brakes. Started furthest away and work toward the master cylinder. Also did Goodridge lines and Ferodo DS2500 pads. I only used 1L of fluid. In previous cars I’ve prepped for track, never cycled the ABS or anything and it worked out just fine.

Hope to see you there!
