Hi,We have a problem with the brakes on our Bedford CF250 van. It is an auto gearbox and the brake pedal seems to be travelling too far, although when I select reverse it would seem that the servo kicks in (for a short while anyway) and when in drive the brakes are terrible again. I have replaced the brake cylinders on the front wheels but not the back yet. Could it be a fault with the servo switch or is the whole unit knackered and how is this related to the auto gearbox?Many thanksPeter.

Hello, when you say it is oak in reverse, do you have to drive it a short way, or is it oak when it is stationary?
Hi, what I meant was when I put it in reverse, eg for parking, the brake pressure is fine momentarily, and then the pedal suddenly travels further than it should. Driving it a short way makes the brakes worse, to the point where you can hear a scraping noise. Maybe I shoudl pull the drums off the back to see the state of the shoes... but my initial question is servo - related.
Relist: Answer came too late.
I think you will find that the rear shoes are completely worn. This will give you the experience feeling of the brake travelling too far, as the wheel cylinders take up the excessive clearance. When these have been replaced and adjusted correctly, you will find thaqt the brake pedal feels ok. Thanks Darren.

Hi Darren,Can you please address the question of the servo? I know it is likely that the rear shoes are worn, but how does the servo operate and cna it be the case that the switch (if there is one) is faulty?Cheers,Peter.
