2200 servo on a 3500?

I know the 2200 servo is smaller, and that the 3500 calipers are 6 pots, but I am breaking a 2200 with excellent brakes and need a servo on the 3500 that I'm rebuilding, so is it technically possible to use the 2200 one?

thanks
 
You will have to get creative with the mountings and it will make the brakes very heavy. I had a TC a few years back that had been fitted with V8 front calipers and I think it made it worse because you really had to stand on the pedal to get any result. What is wrong with your V8 servo? The hydraulic side is the same and can be swapped over which is probably your best bet.
 
so can I swap the slave cylindre from the 2200 servo onto the vacuum part of the 3500?

the v8's been stood for years and I need it on the road asap,

thanks
 
That's right. You need to split the vacuum chamber to get to the securing bolts which is a bit awkward but the vacuum chamber is the only difference between the two.
 
Hello Red,

Don't use the smaller 2200 booster (servo) in a 3500. In 1986 I had a booster installed in my 3500, I was still on my P plates and knew very little about Rovers at the time. The booster as it turned out was from a 2000. The brakes didn't feel good at all and the car was hard to pull up. The pedal was all over the place, hard then soft..aweful. I went to another Rover specialist who upon looking at the 2000 booster sitting in my engine bay said to me...you are very lucky indeed that you did not have an accident. I told him how the brakes felt and they did not stop the car very well. He swapped the booster over for the correct 3500 model.

Upon inspection the booster was at the point of total failure... :shock:

Moral of the story,..don't use a booster designed for a 2000 (2200) in a 3500.

Yes, but the hydraulic bits are identical. Only the vacuum chambers are different.

Hello KR,

Hmm,..not all of them actually. I have two genuine Lockheed booster kits in front of me, one each for the 2000 and the 3500. The vacuum chamber diaphragms are indeed quite different in size with the 2000/2200 being 20cm in diameter while the 3500/3500S is 22cm in diameter. Within the slave cylinder, the piston, piston seal and the retaining band are also different with those for the 2000/2200 noticeably smaller in diameter,..15mm against 17mm for the piston, 16mm against 19mm for the piston seal. The piston seal for the 2000/2200 is also thinner, 3mm against 5mm. Other parts though appear to be the same between both slave cylinders.

hi all,
ron is right. as you know i run rover classics, both the systems as ron says have different sizes. the p5b however uses the same seals as the 2000 / 2200
