Advice on bleeding brakes please

saladdodger · 04-02-12, 07:39 PM

So i have painstakingly gone over everything ive changed, which includes:

All 4 calipers
Rear carriers
All 4 brake hoses
2ft either side of copper pipe
4 discs and pads all round

Ive topped up the brake reservoir as i lost 90% of the fluid, it says in the Haynes book:

Bleed as follows:

Rear right
Rear left
Front right
Front left

But this is the problem im having using a one man bleed kit.

When i push the brake pedal you can hear a woosh of air from the reservoir and the pedal goes right down almost to the floor, even after about 20-30 pumps of the pedal, i opened the bleed nipple half a turn then pumped the pedal again but a dribble cam out, almost nothing.

It does say that the master cylinder might need bleeding, so i opened that nipple and pumped 3-4 times but seems to be so much pressure it pops the bleed kit off.

Also says bleed the clutch system first if its a hydraulic clutch? Mines an AUTO. Do I still need to bleed something.

Am i better off buying a pressure bleed kit that works off they Tyre pressure.

Am i doing something wrong??

Thanks

Andy

also think you need to make sure the handbrake is off....

i use one of these

A clever product that uses the pressure in your spare tyre to bleed air and old fluid from your hydraulic system.

Eliminates the need for a helper as you no longer need to pump the pedal.

Just connect the Eezibleed as instructed then open each bleed valve in turn until new fluid starts to flow through.

Same as what I use and I can't fault it. Don't forget to drop the pressure in the tyre you're using, and the connection to the tyre needs to be the last one you make and the first one you remove (or you'll get brake fluid everywhere!).

yeah that happened first time i used it so iam not the only one

Right O, i'll try one of these kits and repeat the process.

Do you think bleeding the master cylinder first or last?

I usually just get someone to help and never have an issue.

the kit fits on the master so it gets bleed at the same time
put brake fluid in the bottol and screw cap onto the master and the black air pipe goes to the tyre

a friend or lady with at least one ear and at least one leg is perfect!
