Question about 2001 Volkswagen Golf
Mk4 Brake and clutch fluid change and bleeding
First time I've done this on the R and after hearing various scare stories of it taking a while or being a tricky job involving Vag-com etc I thought I'd share my experience today.
Firstly you will need:
7mm spanner - front bleed nipple
11mm spanner - rear bleed nipple
9mm spanner - clutch bleed nipple
length of clear hose - makes clutch bleed easier
Eazi-Bleed Pressure Bleeder - because pedal pumping is for women
2 ltr brake fluid - Halfords Hi Perf 5.1 for me, run it in race cars and it works
spare wheel - for the Eazi-Bleed
R32 compressor - it's in the boot...keep that spare wheel at the right pressure
Ok, this is an easy job to do and very satisfying when done right, improved braking and clutch pedal motion...it should take you no more than about 1.5 hours all in and you should use around 1.5ltr of fluid.
Start off by connecting up the Eazi-bleed as per the instructions, making sure your spare wheel (I used the space saver from my Jag) is at 14.5-15psi. Once you've attached it to the reservoir and are sure there is no hissing (leaks), disconnect the tyre and fill the eazi-bleed with your new fluid. Re-attach tyre to build pressure.
Starting at offside side front, remove wheel, locate bleed nipple, remove cap, attach length of hose (directed at pan/bowl/jug), use the 7mm spanner to loosen the nipple just enough so the fluid starts to flow through. Don't open it too much and always keep an eye on the eazi-bleed bottle not getting too low on fluid). Keep an eye on the fluid coming through the pipe and when bubbles (there shouldn't really be any) have stopped and the fluid seems clear and clean. Tighten up the nipple.
Repeat the process, with front nearside, rear offside, rear nearside...eachtime checking the eazi-bleed bottle (topping up when needed as per instructions) and the condition of the fluid. You should use around 1ltr on the brakes as you're flushing the rubbish dot 4 as well as bleeding them.
With that all done, locate the bleed nipple for the clutch. It's right between the battery and engine and fairly accessible. Again, remove the nipple, fit your pipe, then loosen around 1/4 turn to see the fluid come out fairly quickly..you may want to fill up the eazi-bleed before starting this as it'll take about 500ml to do.
Pump the clutch pedal by hand, it'll go straight to the floor...it's normal. Pump it around 15-20 times keeping an eye on the EB bottle, you should notice some pressure come back to the pedal although it still won't return itself without you pulling it up.
Tighten up the bleed nipple, making sure when you remove the pipe to not get any on your car or paintwork. Disconnect the tyre, replace the reservoir cap and go test your silky smooth clutch.
