I will have all rotors and brake pads on all four corners replaced with a new set and bleed the brakes on my Hellcat. I had the OEM brake fluid flushed out and replaced with Castrol SRF racing brake fluid a few months ago (last year mid-December) and the car has been driven about near 5k miles since.


I had the Castrol SRF fluid put in before I did the one road course track day session in beginning of January. I mostly drag race my car pretty often (mostly every week). My question is, since I’m going to have new rotors and brake pads put on, should I also flush out the Castrol SRF fluid I had put in previously and replace it with another bottle of fluid or is it fine?


I don’t mind to have it done if it doesn’t hurt to do so. Since I track the car pretty often at the drag strip, I figure I ask if it’s necessary to have it flushed out for new Castrol SRF fluid. Let me know, thank you.

I've run Castrol SRF for around 29 years now in my '93 Viper. I used to do a lot of SCCA racing with it back in the day in Central Florida. It is the highest heat rated brake fluid you can buy. The stuff lasts forever. Other than a simple brake bleeding when the pedal got a little spongey after really hot laps at Sebring, there was no need to replace it. I recently drained and refilled the entire system and I can tell you that the fluid that I put in there in 2001 was still crystal clear and the pedal was super firm. No need to replace it since you just put it in. (It's also expensive as hell)

You can seet he car in my thread if you're curious:

I'm a longtime Mopar guy (like from back in the 1970's.) My second car in high school was a 1970 Plymouth Superbird. This was back when they were just an ugly used car that nobody wanted. I have had a multitude of Mopars over the decades including a real 1971 hemicuda ragtop (yellow and white)...

No need to bleed unless it makes you feel better to know everything is done.... My OCD would have me doing it just cuz... SMH, I hate myself sometimes...

Very nice and thank you. Looks like I won't have to change the fluid for a while after all.

Same reason I'm having it done. 😉
I figure I might as well have them bled to make sure any excess air is released from the brake system and get some nice pedal firmness.

I have another bottle of SRF fluid so I'll bring that with me if the shop needs some to pour some in and fill up a bit.

Yes, leave it unless you want to get it on the 100. I "refreshed" mine after a day at Road America, but didn't improve it much, if at all.

BTW, I am not that familiar with the Brembo calipers on the Hellcat but the ones used on the Viper have two bleeders: one on the outside visible through the wheel spokes, and on on the inside in the same position on the backside of the caliper. If you only bleed the outside one, you are not fully bleeding the caliper.
