Oil on brakes

Post by 450FiveString » Sun Nov 21, 2021 9:32 am

Is there any way oil can get to the brakes other than through the final drive housing on a 450 straight with dry clutches?

I've got the clutch and brake out and will replace the brake and the seal on the final drive but that seal on the ring gear looks like a major job. Don't know if that's where the oil is coming from, I hope not. Not sure I want to tackle that.
