Brake bleeding....the lazy way.

I hope 🤞🏼
I’ve got my sons friends car to bleed the brakes on and mines saying it’s due on the idrive so I thought, what the hell, let’s get a tool to do it. Has anybody else used one of these?

Take care because the ABS system needs each compartment in the ABS control unit bled separately.

As Phil325i says, most cars today have high pressure ABS pumps and each circuit/valve needs to be bled in a sequence by using a controller connected via the odbc port to cycle them in order. If this is not done, it can leave air in the system and result in a soft brake pedal. You can try triggering the abs by stomping on the brakes on a loose surface but won't be as good as doing it properly

I’ve looked into this and it seems you’re right if the system has been ‘emptied’ but for a simple flush out it’s not necessary. There are a few videos on YouTube showing how to do it with inpa which doesn’t look too complicated.

I used to have a gun son one like that and it was very good but I can’t find it now so decided to upgrade to one I don’t need a half flat tyre for 😂

Ha ha! The one you linked is probably the one ill go for when mine fails if im honest. Nothing more annoying than finishing your brakes, to realise you now have two flat tyres from bleeding them

You won't have any issues just bleeding as per normal. The only time you have to cycle the ABS etc is when you let the system bleed out with no fluid in the system.

I had this on the X5 when I got all the calipers redone and the hoses weren't blanked off to stop the fluid dripping out.

I just use the old 2 man method with one pressing/depressing the pedal.

I've used a vs820 to bleed the brakes on my f10. No issues and pedal was better afterwards showing that the 2 year old fluid needed changing. I did trigger the ABS motor via ISTA briefly for one circuit but didn't for the other 3.

Sounds right! I had to cycle the abs pump when I had it rebuilt (twice!!!) Once at dealer and once with a proper odbc reader. Good to know that you can still bleed brakes in normal way if system has not been emptied :-)

I used the pressure bleeder to flush the brake fluid today and it was a doddle. The only issue i had was one of the rear nipples rounded off so i had to hammer an 8mm socket on it after the mole grips had rounded it off even more! luckily, it worked. I'm wondering why they are 9mm on the rears but 11 on the fronts! Anyway, i couldn't get a replacement so the 8mm socket hammered back on has got it tight again. Obviously, if i have to do them again i'll order some new bleed nipples before i do it.

The old fluid came out like olive oil and the new fluid looks like sunflower oil, amazing the difference in colour . The brakes are now so much more responsive. I never thought the brakes were bad, which they weren't but they are a whole lot better now. So..... if like me you have no idea how old your fluid is, get one of these bleeders and get it done!

Or give me £50 and i'll do it for you.
