URGENT HELP NEEDED, Brake probs
Bloody typical, I have someone coming on Thursday to view the bus regarding the sale and so I took it out today as I havent driven it for 3 weeks as
when I drive it I dont want to sell it.
Anyway I had fitted all new slave cylinders and the brakes were binding on, I think the brake rod didnt have any play and so wasnt allowing the piston
in the master cylinder to return and so locking the fluid in and locking the brakes on.
I adjusted the rod so it has about 1 mm of play and bled the brakes.
Now when I am driving and put the brakes on there is a clicking from the front right wheel.
I Checked and regreased the bearings and checked everything was tight and adjusted the brakes and still a clicking when I put pressure on the
pedal.
It doesnt click when you are driving only when the brake is on and you are nearly stopped.
Anyone have any ideas.
Cheers
Dave

Sorry, I'm having a 'dumb' day. Is it a singular click, or a click-click-click when you brake?
If at first you don't succeed. Build, build again.

Click click click, it gets slower as you come to a stop.
The drum is fine, I just cant think or see what it can be, the sound wasnt there before I adjusted the rod, but I cant see how that would cause it.
I have also adjusted the rod in and out with no change to the sound.
It only happens when you are coming to about 5-10kmh.
If you put the brakes on at 60kmh, the sound doesnt appear until about 10kmh?????

I don't think there is anything wrong at all. She knows how much time and effort and love went into her rebuild that she doesn't want to go to a
new home where she doesn't know how she will be treated. Might have to stay outside on the driveway in the cold and wet, no more warm shed!:cry

Maybe it's a coincidence and has nothing to do with the rod.
Half-baked idea that just came to me:
Initially the brakes were jamming on. Correct? The jamming causes excess friction/dragging between the rear brakes and drums. This causes brake
overheating and distortion of the drums, which the vans are somewhat prone to. A distorted drum causes a click when braking.
If at first you don't succeed. Build, build again.

I did think of that but how come it only happens when it is really slow, nearly stopped.
I thought it would happen as soon as the brakes were applied?

Its probably being caused by the fact a,
Gyno tried to fix the brake's on a splitty!
"O.S.K"
We make it happen!

possibly not a very big distortion. My beetles drums did the whole click at low speeds.
It's a splitty???? I didn't realise! distorted drums. They were the worst offenders of all.
How about this. The brake has a finite reaction time correct? A time for it to go between floating in air and hitting the drum. When the oscillation
gets faster than the time it takes the shoe to touch the drum, movement is reduced quite a lot, stopping the click from occurring. of course that
means your shoe has a lot more airtime and braking is reduced.
That's my theory anyway.
