Keen to hear your experiences.
My Imperial brakes have gone bad I think. The only component I did not replace/repair is the oval booster. I intend to investigate soon. Soon as the rain stops! been going for a month now!
Also any one have troubleshooting ideas for my original (rebuilt) brakes becoming weak? They were excellent, car was parked for 8 weeks, last quick drive around the block a week ago and they were very soft and weak, like lots of air. My car has silicone fluid from the rebuild.
Any advice in advance a bonus, I will take a closer look this weekend and report back.
Steve.

Location: Southern Sweden - Sturkö island | Check if the hydraulic brake switch gave up on the silicone fluid (it will, just a matter of time).
If this is the case, then you need to install a mechanical brake switch first of all and then plug the hydraulic one. Bleed the brakes again thereafter.
It's not common that the brake boosters goes bad. |

Location: Perth Australia | Booster dewey is a long way from Australia. Sending a booster to the US and back is very price prohibitive.
You could buy another booster in the US, get it rebuilt, then sent, but it would still cost way more than that kit
I pulled the booster apart and cleaned everything up, lubricated it all with petroleum jelly and put it back together, worked fine.
That kit is pricey, but I havnt seen any alternative
The other alternative is to go to the later type master and booster combo and fit dual circuit brakes

Location: Northen Virginia | Michael, it is not pricey, is a complete robbery. The same company sell kits for another boosters with dozen of rubber parts, springs and so one for much much less...
Would be nice to find a company to reproduce this parts |

Location: Netherlands | Someone explain please how a bad booster could cause a soft pedal?
It's a helper-device to lessen the pedalpressure needed to apply the brakes. If it would fail the brakes would simply be harder to apply.
What was replaced and why? Wear? Leaks?
Was the problem also present before the brake-parts replacement?
Is the fluid low when the current symptons occur?
I would start looking for wet streaks running down on the inside of the (a) tires first.
Moisture around the linefittings and junction block. If fluid can seep out, it could also let air in due to temp-variations. Same goes for the wheel cylinders.
Does the brake pedal firm up when pumping the brakes a few times?
Perhaps a missing/failed residual valve(s) in the master cylinder?
Any change with engine running or not?

Location: North Australia | Thanks for the feedback Wiz and Herman and all.
I installed the mechanical brake light switch on advice from you guys in 2014 when I did the rebuild.
Good one Herman, got me thinking about diagnosing whats going on. My problem right now is prioritizing my jobs! The Imp has been on the back burner for too long. I will post up findings, when I get my slack arse into gear!
As to the initial post, has anyone paid the crazy price for one of these rebuild kits and done the job?
Mick is right, too expensive to ship to Dewey. Thieving Mongrels!
Is there another supplier with a better price?
Does anyone know Dewey? Maybe he will supply an Aussie with a kit?
Keen to get the inside skinny on this, as my booster is the only brake component I have not touched, and I want to keep it all original parts if I can.
I think there might be 2 separate companies making these booster kits/parts, one is Dewey, and and I think the other is the type in the ebay ad, but I can't work out who it is. I could be wrong though..........
Steve.

Location: ZH, Switzerland | My oval booster was apart for more than a year. From the pictures in the FSM I couldn't tell if I assembled it correct. But for sure it leaks more than before. Before the disassembly the main leak was the shaft seal at the cover pointing to the firewall. Happy Restoring! Dieter BTW: the price for that kit is almost the same price as at Dewey booster... but for a full restoration; the other one is Karps Brake Service (but the page is down right now)

Location: Southern Sweden - Sturkö island | As Mick writes, most of the times the oval canister booster just needs to be cleaned up and re-lubricated. The last one I did was back in the seventies, and the gaskets was made out of leather if I recall correctly.

Bendix oval booster. Brakes feel like they are failing.
