Owner reviews for brake fluid

The dealer offers $250 of full synthetic oil and filter changes for three years which is pretty solid. The stuff like cabin and air filter I do myself. Just had a brake fluid flush at the dealer for around $300.

I just hit this milestone. here's what GM had to say:\n\n>Drain and fill vehicle coolant circuits.\n\n>Replace brake fluid.\n\nhow much did it cost me? $200

I definitely stop faster then most cars, I upgraded my break fluid to [Liqui Moly SL6 Dot 4 ](https://www.oreillyauto.com/detail/c/liqui-moly/oil--chemicals---fluids/maintenance-chemicals/brake-chemicals/brake-fluid/371c20e7cfcc/liqui-moly-33-8-ounce-dpt-4-brake-fluid/lqm0/22238) I get a lot less resistance on pedal press after the fluid change.

I did some research before each purchase and tried to buy OEM- or OEM+-quality fluids and oils across the board. Motul RBF 600 Factory Line Dot-4 100 Percent Synthetic Racing Brake Fluid

I’ll say I’ve got my fist track day coming up at the end of the month. IS300 pads ordered and I’ll be bumming some quality endless fluid off a buddy. Otherwise all stock for the braking setup.

I’ve got motul rbf600 in mine and it makes it a few months at a time so I don’t even worry about it now. If it feels fine it probably is fine

If I decided to track it tomorrow I’d be running Castrol SRF. Its done well for me in my previous track cars.

I did mine for $15 using BMW genuine fluid.

I've been running the Motul RBF 600 in my C7 for track and autocross. I flush once a year. It works fine.

Ate 200 caused my master cylinder in my M2 Competition to squeak. Wound up having to re flush with OE low viscosity fluid then again with SRF. It's a known problem in a few cars.
