Hello Prado owners
This is my first post here . Has anyone had experience with the load sensing Proportioning vale on the 90 series TD, I had a very scary experience where the front brakes locked up and it appeared there was no brakes at the back even though I had about a ton of camper trailer in tow ( about 120kg on tow ball),.any tests or fault finding tequnices happily accepted.

Hi Grizz. This topic has been hammered before. If your wagon has been lifted, the valve lincage will have to be lengthened to correct brake bias. Like most gear on a vehicle, they are great when they are working well. Persevere with it and fix it - it is worth it. Cheers, Derb.
