Sorry for the novel. Skip to "Here" for the short version.

Ok, I know, it was a very very very stupid mistake. Was installing Extended Brake lines the other night in the dark. And when it came to bleeding time i picked up the wrong bottle, VERY wrong bottle. I mistakenly put ATF (Auto Trans Fluid) Through the system. ATF is Petroleum based and will eat away at any rubber seals it comes in contact with in the brake system as brake fluid is made of Glycol-ether of which is not petroleum based.

Now, my brakes were jammed on and i got a lift home on the back of the truck. when i looked in the master cylinder reservoir and noticed that there was red fluid in it. i thought to my self that that was strange cos the stuff that i had bought was green. I looked on the shelf and found a full bottle of brake fluid and an almost empty bottle of ATF Big sad face.

So removed my calipers and striped them apart and cleaned everything. I flushed the living shit out of the system even used an air compressor on all the lines. Cleaned everything up and put it back together, flushed the system with BRAKE FLUID and took her for a test drive .................... All was good again XD. Went to go for a drive this morning, NOOO......... stuck again.

Here - The short story is that my brakes are f!@#ed from mistakenly putting ATF (Auto Trans Fluid) in the brake system. I Believe i will need to buy new seals for the calipers cos they must have absorbed some of the ATF so that is what i am going to do. Is there anything in the master cylinder that will need replacing? Where would be a good place to get what i need (either online or a store near coffs)

Master cylinder and rear wheel cylinders also have similar seals. Might be better off just replacing all components

Do Jimny's run a LPV on the back?

True, Price from Suzuki (cos there are no after market parts) is 20ea for caliper kit 79ea with pistons, and 159 for master cylinder kit. and I would say that the rear drum seals would be about 20ea as well. So I am potentially looking at $239.00 + what ever needs doing to the LPV.....

Yes.

[want33s]

I don't think you can buy kits for the load valve thing, you may have to replace it.

Are you going to buy a torch now?

You will have to replace all seals after a thorough flush. Metho is safe to use to flush, there are others that may be better. The primary cup(s) in the master cylinder normally sit just behind the compensating port at rest to allow excess fluid to return to the reservoir. The oil has swollen the cup and it now blocks the port at rest. When the brakes are applied and released, fluid is drawn past the cup lip and the excess fluid cannot return to the reservoir through the port because it is blocked... locked brakes.

For brake bits you might try " 4wd_products" on ebay, he's in NSW & has sent everything to me in Brissy overnight !!!
He hasn't failed to find me anything I've needed so far.

[suzooky87]

Turns out that there is no aftermarket rebuild bits, have to order through Suzuki. And yes the main issue seems to be the master cylinder, there might be after market bits for that though. I will be replacing all seals. Apart from the Rear and the LPV unless i Have any problems as non of it made it to the rear. It took quite a bit of bleeding to get any red stuff to come out.............lol, anyway. Lesson learnt, bought some work lights today and will be using them! and i have arranges the shelves so i dont get anything mixed up. Still cant believe what i have done................

Yeh, thanks mate. I called them and they had nothing for the calipers or the master cylinder.

[Scrawny]

Expensive lesson but undoubtably well learnt!

Dont be too hard on yourself, easy mistake, i once did the reverse and put brake fluid in my power steer reservoir.

That sounds great, but i kinda want it asap.......

[BlueSuzy]

I have a booster/master here off an 00'm13a jim. If needed. Used, But was in good working condition when i removed it as i drove the car with it in... Pm me

[suzooky87]

Found a master cylinder from my local wreckers for $40.00 XD Going to buy the seals from suzuki for 40.00 also. all up $80.00.

[BlueSuzy]

Sounds like your winning! Nice work

[suzooky87]

Yeh mate, just trying to sort it out before the weekend, thanks for the offer though

[suzooky87]

Is metho truly safe to use to flush the system?

[zuk85]

not 100% on the metho.. shouldnt do damage too the hardlines, but rubber maybe another story.

But maybe you can use just water..since its water" moisture" that is absorbed by the brake fluid anyways" hygroscopic"
so since the lines and such have had water in them before, not such a vast amount obviously. but it shouldnt do any damage just clean if you flush with BRAKE FLUID thoroughly afterwards so no rusting ouccurs.

but still wat everyone else has noted needs to be done, changing of seals and other gear. damage is already done. sucks but there sounds like there is light at the end of your tunnel.

[lordviper556]

you can deff get kits for the calipers i have rebuilt mine.

also i wouldn't run any water through the system, as you said atf fluid is petroleum based so water wont do shit. id flush it with a few bottles of new brake fluid.

Done and done, new master cylinder in and one bottle down the shitter and going to get new seals tomoz so i will run an other bottle after i rebuild the calipers. Might even scrap that and put in Vit LWB calipers so i can run vented and bigger brakes thanks to the research of Mr 31zook XD

Yes, metho is good for cleaning and flushing the components and lines and will not harm the cups, seals and rubber hoses. It evaporates quickly as well. Don't use water, you don't want water in the system as it reduces the boiling point of the brake fluid and supports corrosion. Don't use any mineral based oil or cleaning agents as these will harm the rubber components and even a small amount mixed with the brake fluid will cause harm. As said, you can buy special cleaning agents for brakes, but metho is cheap and has been taught at tafe and used by mechanics since cars began using brake fluid.

[suzooky87]

Sweet. will do this today then

[BlueSuzy]

Its funny that everyone says Ethanol dirty/bad/shit for rubbers in fuel systems.

Yet metho is good. Every metho container ive bought recently Ingredients is Ethanol.

[boostedbrick]

The water content in ethanol will effect steel components in fuel systems, since ethanol has been around since the mid '80s I doubt any recent manufacturer would be using materials that could be affected. Its pretty much the same with rubber, allot modern rubbers don't give a shit about ethanol.
