I thought this might be handy for some of you guys.

The most effective way to bleed the brakes and clutch on your VX is to use one of these:

Sealey Power Bleeder® Brake Bleeding System

One-man brake and clutch bleeding the professional way. Bleeding requires no external power source - simply fill and pump. Reservoir holds 2.5 litres of hydraulic fluid - flush the entire system with one fill without the risk of running the reservoir dry. Pressure range makes unit suitable for use with ABS systems. Fitted with Ø42mm cap and suitable for most European models. For other applications order optional VS820UA Universal Adaptor.

List price £105.69


The idea being you fill it up with new brake fluid, fit it to the brake fluid reservoir, pump it up and the pressure forces the fluid through the system, replacing the system and expelling any air as you open the bleed nipples one by one. Except, that's a bit pricey for my liking.....

So, I made one myself :)

Parts required:
ASDA Power Sprayer
Spare fluid reservoir cap
Araldite

Simply purchase a pump up garden sprayer from ASDA for £10 and chop the end off the rubber hose.

Buy a replacement fluid reservoir cap, I think one from pretty much any car will work, I two from a local scrapyard for a pound :)

Drill a hole in the cap so the hose fits through with as snug a fit as possible. Poke it through the top with about 5cm poking through. Put some a liberal coating of araldite on both sides of the hole to secure it and make it air tight.

If you then cut off the protruding bit so it just reaches the maximum mark on the reservoir, then whenever you have finished bleeding the brakes, and release the pressure it will automatically siphon the fluid down to the correct level, providing the bleeder is lower than the reservoir.

Let it dry and bingo, you have your own pressure bleeder for a smidge over a tenner :)

Looks like a good idea thumbsup But could putting pressure from the resevoir side damage the master cylinder / seals :blink:

Nope, the eezi bleeder has been around for years and that uses air from a spare tyre. You only need about 15-20psi which is hardly anything, just enough to push the fluid and air through. Similar pressure bleeders are used at the Ferrari/Maserati/Bentley dealership where I work too.
