Brake fluid flush and change - feedback
« on: 29 August 2006, 21:15:06 »

Tunnie,

Great maint guide!  well done.

Started a new thread so as to keep things tidy.

You have done a great job on describing this really clearly,  only doubt on my part (never having touched brakes before) is the bit about removing the fluid from the calipers.  Not sure I fully got that bit, but then that's probably just me :-[

Give a few months and the H book will be a thing of the past!  :D

Cheers
Merv

cheers mate, i started a thread in gen chat to discuss it, if Jamie could delete that on and we stick with this? Thanks


Yeh sorry about the vagueness off the actual caliper bleed. It will become more ovious when you look at it, does anyone have a picture of the caliper bit??

Tbh just flushing the fluid and not doing the caliper bit, makes a big difference. Its just not the full correct way...

And the big reason for changing the brake fluid is that the fluid gradually absorbs water over time.

New brake fluid boils at something like 300C, old brake fluid boils at something close to 100C.

Some hard braking with old fluid and the fluid boils, you are braking with gas = no brakes.

Brake fluid should really be replaced every other year - more regular if you do big miles...

Excellent How2 Tunnie.  Well done. [smiley=thumbsup.gif]

I noticed you have however missed out the final, and probably most important part, 'Once complete, sit back and crack open an ice cool can of beer.'  ;)

Just wanted to add my thoughts:

A great guide and excellent pics.  Having pics really does help IMO.

You say that you prefer the two person method.  Have you ever tried the Gunson easyblead?  I have used this device many times with great success, although not, I have to say, on any of my cars as I have always fought shy of bleading an ABS system.  On my Transit vans - it is just the job.

One other advantage of changing the fluid - as we know it absorbs moisture and this can have an adverse effect on the valves of the ABS soleniods.

So, well worth doing all round!

Once again, great guide.

I have had various 'one-man' bleed kits, but always go back to 2-man method for various reasons. Usually, the kit never works as well as expected, esp after first use...

Also worth pointing out that the Vx official brake fluid change interval is 24 months, though as usual we recommend more frequent servicing...

I have to admit that I have found this.  Kit works great then after a year in storage just does not "cut the mustard".  However, I don't have any willing helpers so have to do the work on my own.  Therefore, I just buy a new kit every two years and time all my vans so that their fluid needs doing at the same time.  I have rather an extensive collection of esasy bleed bottles and washer sets!

Still, always work for me just fine.
