what happends when ur friends grandfather puts tranny fluid (on accident) in the brake master cylinder of a 88 M*****g? can we just bleed all the fluid out till we see clean brake fluid in? or do we need to start replacing calipers and hoses?

spare the mustang jokes guys.

I think as long as it didn't get driven too many miles you should be fine as long as you get the system flushed and filled with new fluid. should not hurt too much.

 

i don't think its been driven any miles, oh well i guess tomorrow we'll have the answer for all the other people who experience this..

I don't know, but I saw my neighbor put motor oil in the power steering pump of his daughter's car!He was horrified when I told him there was a difference! He spent the next few hours trying to sponge it out of the resevoir with rags.
It'll probably be fine as long as you get it out of there before it gets driven.

i think tranny fluid is petroleum based and if it is your friend better plan on replacing avery rubber piece in the brake system,(primary and secondary cups of master rebuild calipers and wheel cylinders) and anything else i forgot. he will need to do replace all the rubber parts because petroleum based anything weakens the natural rubber of the break system and can cause them to fail.

Brake fluid isn't petroleum based? I thought all hydraulic fluid was...?

actually way back in the day they used trans fluid in the brakes, i dont think it would do anything bad, i would just leave it, if it does have problems, then bleed out the system.

 

I don't think it's a good idea to leave it...at least get it flushed and refilled with brake fluid. It's better to be safe than sorry when it comes to brakes...

 

i know that brake fluid is not petroleum based it is silicon based. but the trans fliud is petroleum based and will destroy the rubber in the brake system. and cause the sytem to fail. putting tranny fluid in is just like pouring oil into your brake system, they will both devistate the seals

 

I know it's not advised but a friend has been using plain 50 weight engine oil in his powersteering pump in his 350 powered 85 chevy truck for the past 10 years because powersteering fluid leaks out too fast and he's too cheap to get it fixed,he says the engine oil stays in it a lot longer before he has to fill it back up, this same guy also has not changed the oil filter in the same time period either, he just adds oil when it gets low.I think the truck has about 200,000 miles and still runs like new!!

if the trans fluid is just in the resevoir and the brakes havn't been pumped then you can probably just flush out the master cylinder, fill with clean brake fluid and then bleed the system out. while petroleum based fluid may damage the system I don't think such a small amount left for a short amount of time will hurt any thing.

 

Well, I'll be the bearer of bad news, you're in up the creek without a paddle. Every seal, cups, o-rings..EVERYTHING rubber is now screwed.

wut if the brakes haven't been used, and it still in the resovour? if we're still screwed, then do ya think junkyard parts would hold up?

Although the ATF might eventually ruin the seals, I can't believe it would "kill on contact". If you flush out every trace of it, then you'll probably be fine. Just keep an eye on it.. if you start to get a soft pedal then by all means, replace the master cylinder.

If you only applied the brakes a few times, who's to say the ATF even made it down to the calipers? If any seals are destroyed, I would think it would be confined to the master cylinder, FOR NOW. Just make sure you bleed it ALL out!

as stated before if the car has not been driven or more importantly the brakes not been pumped just remove the master cylinder. no damage has been done to the system since the fluid has be confined to the master cylinder. might as well replace the master while your at it.

 

ok, thanks alot guys, we're procrastinators so we still haven't gotten to work on it yet.
