:Getting on Soap Box:

Part of my spring ritual is to replace the brake fluid.... (just did it this weekend)
I was just wondering how many realize that this needs to be done periodically...

Moisture & air are the problem.
There are many ways for moisture to enter your brake system.
Condensation from regular use and humidity are the most common, with little hope of prevention.
Glycol based DOT 3 & 4 fluids are hygroscopic; they absorb brake system moisture, and over time the boiling point is gradually reduced.

It's really an easy job to do & yields immediate bennefit.
Pedal pressure really firms up & the brakes are much easier to modulate.
Stopping is definitely improved.

If you want to read a little more.... Stoptech has some great whitepapers

 

Ian,

How much brake fluid is required to replace / bleed the brakes on the sedan? I still have two bottles of Motul RBF 600 left I think they are 500ml. Do you want to do my brakes

 

2 bottles is right, you'd actually have a little left over.
(note: left overs get tossed once the seal is broken)

I usually do mine when I switch over the snows to summers,
since it's up on stands anyway...

I use to two person method..... don't feel like spending $ on a bleeder kit.
There are many DIY links arround... like Stoptech's

But if you're not comfortable, it's not expensive to get it done at a garage.

Oh & you can't afford me... LOL (I can eat & drink a lot)

 

if you're gonna do your own brakes, I highly reccomend speed bleeders. Since I have StopTechs I've got 8 bleed screws to deal with instead the standard 4, so the Speedbleeders save me a bunch of time.

 

Thanks.. good tip

 

When you have 2 bleeders per caliper which one do you bleed first, outside, inside, or does it matter?
Thanks

 

I want to know too.

 

You should always bleed the outermost component of your system first..Same principle used with the calipers. Furthest from the MC.

 

I think I read somewhere that it really isn't necessary on modern ABS systems. Although I still practice the method you mentioned. Just thought I'd bring it up for debate, if there is one at all.
