Hi,

I drive a 90 pajero with 4d56 diesel engine.

I find that sometimes when i apply the brakes, for an instant the vehicle drags to the left and then stabilizes to normal on continued braking.

Looks like the left pad is applied an instant before the other side applies and then it equalizes.

The front brake pads have been recently replaced and there is no contamination.

Are there any valves that could malfunction and lead to this sort of symptom.

Cheers,

Hi, are you sure it's not the right brake piston sticking until the pressure is on the left pad?

I would go along with that, offside piston sticking momentarily then coming on. There may be a bit of rust forming on the piston itself causing it to stick. Its not a particulary hard job to do, just need to be clean and careful.

Thanks guys,

It definitely gives me a different perspective on looking at the problem. Infact when the pads were replaced, the pistons were cleaned and rust on it was removed.
Guess it is a good idea to give the right piston another look.

BTW does anyone have an idea what this unit (it says AISIN) on the rear brake circuit is. is it a metering valve? It is mounted on the inside od the chassis frame.

Cheers,
