Brake Fluid Tester from the Bay

[Paul H]

Just received a Brake fluid tester £3.80 deld . Needs an AAA battery 

The calibration <1% <2% ok

<3% <4% change fluid 

Tested my Vitesse ( Dot 4 last changed 3 years ago )

Brake test ok ie less than 1%
Clutch test ok but 2% so marginal . 

To get reading completely immerse the pins 

Should I change Clutch fluid ?

I would do it when the brake fluid needs it as then you'll have all the stuff out. Worthwhile due to the risk of corrosion in the clutch system...

Yes. How easy is it? Simple, cheap to do, and peace of mind knowing it's done.

So why worry about percentages and figures? 

[Paul H]

Thanks will change clutch fluid . Re brake fluid change . What’s the procedure to minimise getting air into the system .

its a general recommendation to change every 2 years ,  a lot depends on use ,car storage etc   you may just need a turkey baster and suck 

out the reservoir  ...thats a bit mischievous  with little usage that's where the moisture gets absorbed via the cap vent through normal breathing atmospherics

...................the best advice is yes flush some new through ,  those testers do give a good indication , so go with the result ..at least you are aware

the procedure is to just flush through with a soft pedal action  and dont let the resv empty then no air will get in  

i always advocate have the catch bottle high above the brake keeps the tube and nipple threads air free

I just use gravity Paul and when clean fluid comes through tighten up the bleed nipple.

Hi Tony . Brake fluid is still clean so would have to measure before stopping

3 or so pumps of the pedal in each corner should swap old for new

well if youre going to open a bottle make sure you use as much as possible cos your tester will probably indicate its no good next time you want it😆

It just looked a bit murky the photo Paul, so it would be a bit difficult.

I aquired a vacuum Bleed kit. So far it has worked very well with 5 metre of brake pipe to the rear`s it makes for a simple one man job. I change the brake fluid every couple of years, ever since I lost braking on an incline, due to the fluid vapour locking. VERY "brown trousers". Spent all weekend changing the fluid on a campsite. (behind a pub).
