As far as i know, there are no known radials in that size, but then Professor Crump might prove me wrong
Serious drums all around.
They seem to stop quite adequately, but I would not want to go racing around the 'Creek' with them...
There are no radials made inthis size. There are truck radials that some people fit and they improve straight line tracking but are so wide that they make steering almost impossible. The long term solution is to fit 4WD radials and a power steering kit but that will take some time. Long term will see a complete overhaul and the fitting of power steering, an overdrive and airconditioning. I will have a few more grey hairs before all that is accomplished.
The brake servo runs off the gearbox and is exactly the same system that Rolls-Royce kept on the Phantom until they ceased making Phantoms in the late 1990s. It was also used in Clouds until the end of the series. The brakes require a heavy shove but in a brake test against the CLK they proved to stop in about the same distance. The set up is such that the front can not lock. As soon as the front brakes start to lock the servo looses power from the front to avoid a front wheel skid. The servo also proportions the braking between front and rear depending on the load in the car. Brake fade should be almost non-existent given the size of the drums and the depth of material but it is critical that the system be set up properly and it requires re-setting every 500 miles.
Now for some trivia. When the car was built in 1933 it came with a 3 year, unlimited mileage warranty on all aspects of the vehicle. That included sending a technician anywhere in the world to repair it and sending you home by first class passenger liner should the vehicle not be repairable within a reasonable time. That same warranty applied to the Spirit in 1993. And the best some manufacturers can do now is still 2 years and you have to beat the service department with the leg of a dead lamb to get that....
Oh and by the way, I am assured that the steering will get lighter now that we have managed to repair the Bijou and are dripping oil again (Bijou one-shot lubrication system - lubricates the chassis with SAE30 oil and you give it a pump every time before you drive the car). I suspect a rebuild of the steering box might be in order though, or perhaps even a new one, yes, they are available.
