Brake Proportioning Valve for FJ40

[LR LC200]

So did you do the conversion? Do you know if you put a new porporioning valve on when you put the discs on? I didn't do mine so I don't know what the stock valve was like but here's what I know: as far as I know you should only have one. It will be by your brake booster or master cylinder, you can follow back the brake lines to it. My stock 60 has it up bolted to the booster on the same bolts that bolt the master cylinder to it but that is not adjustable so if you have that set up most likely it is going bad and needs to be replaced. If you find an adjustble one (mine had a knob on it) play with that knob till it feels right. The porportioning valve basically just controls where the fluid pressure goes to first.

Yes conversion kits been installed, no proportioning valve. Question is whether if I reverse the brake lines will it have the front brakes activate first given the rears lock up 1st now. Is there a safety reason why this is not a good idea?

Thx,
LR

I mean you should almost definitely find one...do your brake lines do directly to your brakes from the master cylinder? I'll take pics of mine

Oh and I should say if you really don't have a pvalve then you should have one and that there is your issue

May be... I think I kept the original MC. Will check and see if there is an external pvalve, but don't think so!

It is my understanding things won't ever work without a pvalve especially if you kept the Mc if you don't have one then you need one I got a awesome wilwood one from summit
