Bleeding brakes

[WIMPUS]

Hi!

I want to bleed my brakes

My original master cylinder is rebuild (tandem) , new brake lines , new rear brake cylinders . i've also got a PDWA valve, but i hope that my front calipers are not seized ..

So where to begin ?  :) I know already that you must press the brake pedal slowly for the pdwa valve  ;)

Kind regards Wim

Wim, I think you start at the wheel closest to the MC and work away, I'm sure others will confirm or shoot me down :)

Wim,
Firebobby has it backwards. Normal procedure is to work from the farthest to the nearest. So, right rear, left rear, right front, left front. This even works on RHD cars as the brake piping layout still makes the RH lines longer. It does no harm to bleed them out of order, but you might have to bleed some twice.
                                                                              All the best,
                                                                              Paul

Wim, did you fit new seals in the PDWA valve? That's the one part of my brake system I haven't rekitted yet. The seals available online seem to be for Stag PDWA valves - the GT6 PDWAs have a screw fitting at each end. of the cylinder, the Stag versions only have a screw fitting at one end.

Dag Wim,

I bleed brakes alone!  ;)

You can get many different kits for this (there is a thread recently for this, can not remember which section now)
But I use a long piece of clear tubing, and a bottle, my brakes are allways perfect!

The original GT6 ones here were as you describe.
The GT6 replacement PDWA from BL or JRT available from around 1980 on had the screw cap at only one end, & a sort of stubby lump at the other.
