Knock in Front Brakes/Suspension?

My 2005 Prado GXL has recently developed a knock in the front end somewhere. The sound is like hitting the disc brake with a hammer and only occurs once. It usually happens after the vehicle has been standing for a bit and usually when reversing and after moving only a metre or two and immediately after touching the brake. It's a bit hard to explain exactly. I had a service today and the mechanic checked all the suspension bolts, springs, shockers etc, but noticed the brake pads have a small amount of play in the pins that hold the pads in place. There are marks on the edge of the pads which indicate that it might be the cause. The vehicle has done 110,000 kms and still on the original brake pads.
Has anyone had something similar on their Prado? I would welcome your thoughts.

Re: Knock in Front Brakes/Suspension?

Had the wheels/brakes been wet? I recall a thread on PP that disucsses the same or a similar issue where the brakes had become wet (usually as a result of washing) and have stuck and when they release there is a bang.

Have a look here:
Thump noise when stopping. (Tailshaft clunk)
The difference in this link is the noise is reported from the rear of the vehicle.

thanks for the reply. No the brakes are not wet when the knock occurs. It's definately coming from the front.
Cheers

Geez....you just answered my question. I have this same issue and it is worse in the wet! Any idea how this might be resolved?
