MY06 Cayenne S brake fluid flush

[RJFabCab]

I have much experience on 996 brakes and recently changed the front pads on the Cayenne S. Now, I'm about to flush the Cayenne S brake system with new ATE Typ 200 DOT 4 fluid.

Renntech search yielded one pertinent hit RE MY2004 Cayenne brake flush and Loren's response was that the procedure is basically the same as a 996. Cayenne manual states that the flush takes about 0.95 liters.

A couple of Q's:

1. Do the same pressure rules apply for the Cayenne? Keep the Motive bleeder less than 20 psi at the master reservoir?

2. It's a Tiptronic. Are there any other lines connected to the brake fluid reservoir that need to be bled besides the 4 calipers?

Cheers

I sent you a PM.

I sent you a PM.

Thanks, Loren. I did the right rear and then it started to RAIN!!! LOL So, I just moved the truck inside the garage... and onto the left rear. Since I'm working solo, I'm not pumping the brakes while bleeding.

When I moved the truck inside, the pedal felt fine. I use the Pepper to tow and noted quite a bit of debris in the fluid at the right rear (15K miles on the odo) but no bubbles.

I can't imagine the pumping the pedal procedure being necessary unless there was a significant amount of air in the system.

Thanks again for the help. :renntech:

I completed the brake fluid flush with ATE Typ 200 and a Motive power bleeder. It was a little difficult to keep an eye on the fluid level in the reservoir due to the gold color and the hidden nature of the reservoir, but the procedure was very straight forward.

I could have done the entire job with one liter, but I wanted to be extra thorough with all the bubbles and debris flying out of the nipples, so I ended up using 1.25L. Interestingly, "ATE" is molded into the brake fluid reservoir.

The only point of interest, sort of, is that the factory routes the brake pad sensor wires through the rubber covers for the bleed nipples as shown below.

Hi, the service manual is calling for 2.0 bar bleeding pressure which is roughly 30psi

however the motive power bleed tool use direction says not to exceed 20psi

im confused...

[Loren]

20 PSI should work fine.

[TopGun2000]

just did the brake bleeding job. yeah, even 15 PSI is enough ^_^

the old fluid was so clear, i couldn't tell when the new fluid came out :unsure:

it's embarrassing that i almost used up two liters of ATE fluid. not sure if the last caliper was bleed completely since i stopped early in order to keep air from getting into the brake line...

Can i use ATE Super Blue Brake Fluid instead of ATE Gold Brake Fluid Type 200? So it will be easier to spot the new fluid.

Yes, but I don't like Super Blue because over time it will dye your (plastic) lines and tank blue.

ATE Gold Brake Fluid Type 200 has exactly the same properties as Super Blue.

Loren, can you PM me the info you sent the OP when you have a moment. Thank you. 06 CTTS

Also would (2) 500ml bottles of brake fluid be enough to flush or should it be (3) bottles.
