the pushrod does not screw in and out .
It has a half ball on the end that is loose from the master cylinder piston.
Just pushes on the piston when applying the brakes.
I feel the problem must be with the booster as without the engine running the brake pedal behaves normal, except for the initial low pedal.
The booster seems to put the whole system under pressure.
My old master cylinder is identical to the new one fitted now. The booster
has been fully reconditioned. Bear in mind that the booster and master cylinder are not one unit. The booster sits on the opposite side of the engine and has got its own (sort off) master cylinder that feeds the brakes.
It is fed by the master cylinder that is operated by the brake pedal.
Matt, it has been some time. The problem with my booster was a cracked
rubber elbow between the air valve underneath the booster and the pipe that runs to the back of the booster. This was letting air in and activating the boosters slave cylinder.Simple and now fixed.
Do I have another free question?
My Wolseley has a fully recon engine. rebore etc.
It runs fine but blows a lot of blue smoke after it has driven slowly or has been idling for a while.I though it was valve stems but these are also new,
guides and seats.
It has only done a couple of hundred miles.I am using Penrite HPR 30,
20 w 60, a mineral oil with zinc. I did not think that you had to specificaly run it in nowadays. One difference with the original pistons is that the new ones only have one oil ring (cast iron) as the old ones have another oil ring at the base of the pistons.I have never had this trouble with other early type engines that the same people reconditioned for me.

I thought I could have a few more questions for my initial $35.
Now they want more money when I rate you. Is that correct?
