Brake bleeding the 2.7s with a pressure bleeder

[Ivelosttheplot]

Hi all

i just purchased a sealey vs820 pressure brake bleeding kit to bleed a new and empty system

on pressurising the system or trying too it blows fluid out of the reservoir overflow

should I block the overflow or am I missing something 

it makes sense it would blow out through the overflow but nowhere does it mention any overflows in the manual

the resevoir is new as is the whole brake system

regards Keith 

1976 2.7s by the way

Hi Keith,

Yes you need to block off the overflow.

You have to block the overflow.

Phil beat me to it!

Ps you should have a flexible pipe fitted to the reservoir overflow that is connected to a metal drain tube/pipe, that exits under the near side wheel arch close to the washer tank…

Yes, crimp the hose and go no more than 5 psi

And just in case you have problems closing off the overflow……

Thanks for all your same replies

it’s fairly obvious that the pressure would not hold with an overflow open tube, I should have realised that , 

I’ll blank it off and keep the pressures low

i have 2 bleed valves on each caliper so will bleed from the outside first

Got 6 pot calipers front , 4 pot rears

cheers
