Hi all,

I'm going to be bleeding my front brakes once I've replaced the calipers, and I was wondering;

Does anyone know the correct size tubing that will fit over the bleed nipples and not let any air in? This is on a stock 8.4" caliper.

This might have already been answered, but I couldn't find it anywhere

Thanks,

Simon.

You'll probably end up bleeding the rears a bit too, which have different sized nipples. To be honest, even if the tubing is a fair bit too small you can usually force it on anyway.

I'd say about 4mm internal diameter is about right to get a tight fit.

I've never 'tubed' bleeding nipples (on a mini).

I ended up just finding old tube from somewhere, mike is probably about right though, I had bigger bleed nipples on the rear drums so I just put another piece of tube in boiling water and forced it on to make a tight fit.

Great, thanks Ryan and Mike.

Jaydee - what did you do to bleed them then, if you didn't use a tube?

Thanks,

Simon.

Open spanner and an assistant pressing the pedal. Never had air back in the system.
I can see the need of a tube if rear lines are full of air so you cant bleed them, and you'll use a tube to suck oil from a can and prime the tubes.

The main reason why I used a tube was on the end into a brake fluid bottle so I didn't lose it all over my drive

Good point if you're working on your drive ryan!

Good point if you're working on your drive ryan!

Saves you putting your hand in your pocket to buy some more fluid as well!
