People,
My wife has a Suzuki Sierra 93 of origin, the problem is that the brakes are a bit sharp and also the rear brakes in some cases mainly when the raods are wet, seem to come on before the fronts, I've fitted new pads and used emery cloth to clean both sides of the disc, checked the run out but this would show as vibration, all were good, I've checked the condition of the rear shoes and adjusted as needed, they have plenty of meat left on them. There is a LSPV ( Load Sensing Proportioning Valve) at the back, is the problem I have related to this valve? Is it something else? Does anybody have any experience with these little beasties, in particular a the problem I have? Thanks in anticipation.

Have you replaced the rear shoes.The original friction material on these and many japanese vehicles is made by a Japenese company called akebono it is a very hard wearing shoe and in some cases will do more then a 100,000 kms.The only problem is that it gets very hard after a while hence the longevity.Try a new set of shoes for around 25.00 dollars its not that bad place to start.The load sensing valve generally gives no more problems then leaking externally there is not a lot in them and they are usually trouble free.Just a quick last note this problem is going to be come more common on rear drum braked vehicles as asbestos is fazed out the non asbestos linings are still not as predictable as the old asbestos and behaves differently hot to cold and visa versa.Gotta get out there.

Michael,
Thanks for that, I'll get some shoes and see what happens, together with bleeding the brakes, the cars done 153,000 I think so it's done a tad more than the 100k. I wasn't sure what was in that valve or if it was a common failing point, the manual says just to buy a new valve if you suspect it's faulty.
All cleared up thanks, I'll let you know how I go. Keep the shiny side up

Your rear diff isnt leaking oil onto the rear shoes is it? If i has/was/is the pads will soak it up and you will need to change them.
If there is nothing out of the ordinary you can see, check out a brake specialist.
