Brake Proportioning Valve

CraigNZ · Post by **CraigNZ** » Sun Dec 04, 2005 9:50 am

Anyone ever had any issues with this valve? My front left is locking when I brake hard. I have changed the pads and even put another disc on but still locks. Have not got the gear to do a test on the valve but I suspect its letting the front left have too much pressure. Are they fixable or is it a replacement job ?

Thanks

Hi Craig, apologies for the delay replying to your email. Found a way to post up the brake diagrams for all to see

Ok, its the part with the red square around it. The layout shown is about right, the biggest issue with swapping it out is actually getting at it. Its mounted on the firewall - smack bang in the middle. You'd have to either pull your intake manifold off or get at it from underneath.

Also note - the number indicated in the picture is NOT the part number. If you can tell me your chassis number (Ie HNHM, HRHM etc etc) I can give you the correct part number - as there were different types on different models.

As with most Hydraulic valves, chances are you could reco it, but being such a small unit & being part of the brake system, I'd just swap it out. It couldn't be that expensive. Give Peter at Kempys a call seeing as your in NZ (09) 295 0088

I'm not sure if any of you have been told yet but Peter is leaving Kempy's sometime soon.

I'll try them both and se what Peter has to say.

See what you mean about getting to it!! May have to remove the intake as you suggest.

Take it from the diagram that there is no load sensor on the rear ?

Thanks again

Yep, there's no rear one. This one valve does the lot by the looks of it.

Thanks

Will let you know how I get on.......

Looking at the diagram, my brake pipes are not connected in the same order.
From the front the bottom right goes to the front left and the top to the back. The left hand bottom goes to the back and the top to the front right....

Unsure mate

Never had to pull mine out....

Oh well...........just have to swap them over and see what happens

Well, I swapped them over and its fine now. Can only presume that the valve has been changed at some time and the pipes were fitted incorrectly !!

Thanks for the help, the diagram was a lifesaver...

Cheers

Craig
