I just got my Dodge truck home and found out the the former owner ( the one before the guy I got it from ) seems to have put ATF in the brake reservoir. I feel that Im going to have to replace everything in the system and blow the lines out to get it out is this overkill ? Will just a flush do the trick ?
thanks

I'd drain and flush as best as possible, then wait to see what fails, and replace parts as (if) they fail.
how long has the fluid been like this ? a short time shouldn't be an issue.

The best thing you could do is reverse bleed the system (push fluid from wheels to master), and then just replace the master, as unless they bled the system with the trans fluis in it, very little, if any ever reached the wheels.
 
This truck sat for a while. I so I would say its in the whole system the brakes have all ready gone out so something has failed. Im planning on using it as a tow rig so losing the brakes would bring new meaning to the word suck :eek:
 
Ah, thats different

may as well figure on master, calipers and wheel cyls.

I hope it is old enough that it doesn't have ABS, or it's gonna get REAL spendy.

As for things failing, RARELY anymore will a system have a TOTAL and sudden failure that cannot be felt before hand if you are paying attention to your vehicle.
 
cross-contamination

Replace everything with a rubber seal. 100% of the hydraulic is or will be smoked soon.
 
no shes an 81 sweet and simple I think im just going to replace everything and blow the lines out seems the smartest and safest way to go

"Check for brake fluid contamination. If mineral oil such as engine oil, power steering fluid, or automatic transmission fluid (ATF) has been used in the system, the rubber sealing cups swell and can block off the compensating port. If contamination is discovered, every brake component that contains rubber must be replaced"

Pack a lunch and open yer wallet, gonna be a long weekend
