I have a 1972 Toyota hilux with the original front drum brakes...I want to do a disc brake conversion on it....what years are interchangeable?? and does anyone have the parts for sale to do it with??
79-83 spindles will work too, flip them left and right so the steering rod is at the back. You need to swap the brake master and rear proportioning valve from the same era trucks. Your master is setup to feed 4 drums. It'll work, but not very well. I've driven half swaps. Do it all the way the right way buddy.
Good to no ill be doing this soon i want to do a drop spindal so i dont have to z the frame i was looking at the front main cross armfor the susp and i could cut down and modify it 2 or 3 intches into the cross bar to drop the front without a z i got it messured to tuck 18s or 20s just not sure how far i want to go with it fully custom or just a easy classic
So are the 79-83 spindles the best way to do it? Does anyone have a list of thing I would need to do this swap? I have a 1973 that needs better stoppers.
79-83 is the same spindle as 75-78 just flipped side to side to have the steering in the front not the back. Grab the brake booster and master too, and the prop valve under the booster. There is no drop spindle for this generation. An 85-95 will need the lower balljoints flipped upside down to fit, but should otherwise work. I haven't done it yet so I can't totally confirm. And raising the crossmember into the frame is a great idea, but don't forget to raise the center link the same. That means the idler and pitmen arms. Either by raising the bracket and steering box, or by heating and flattening the arms. Again, I haven't done it so that's just my plan/theory. But the tie rods need to stay in line with the lower arm or you will cause bumpsteer and other bad issues.
If you get the spindle and caliper bracket, the rest can be bought new. The hub, disc, bearings, races, seals, dust caps, calipers, ect. Might be worth swapping some or most of the old parts anyways. And if you flip your lower balljoints upside down, you can run 85-95 spindles flipped side to side. Camber adjustment may be needed, I haven't done the swap yet.
I'm going to bring this back to the top. I pulled a set of spindles from a 1980 and went to mount them on my '73 and found that the hard lines on the spindles point the wrong direction. Am I going to have to bend up a custom set to make this work or can I find them already made somewhere? Was pretty disappointed that I didn't look before I pulled the line off of my drum, now I have to bleed them for no reason....
I found a complete swap bolt on from a 78 i got everything for $250 shipped, near you!! ;-0 I mean complete from brake master-disc brakes to spindles hoses,etc. i will be doing a build thread hopefully..
I scored a complete front disc set up from a 1978 Hi. Everything spindles,disc,pads,rotors,hoses etc. my question is my 73 Hi has a brake booster on it already, would i need to change any thing there? or i can do what i did on my Courier removed the valve on the master cylinder for the front brakes.Worked perfectly, and spent $0. I will do the conversion first and try the discs like that first.I will post pics as i go along.
So is this the proportion valve? (Off a 1978) How does it work? I thought it would have two lines that would go through it which would some how regulate between the two of them.
I don't know if this is true or not, but I was told the spindles I pulled from the '80 won't work as they have caster built into them and when you flip them it puts the caster out of spec. Is this the case or are they really just the same?
I too am curiouse to know about the camber, I'm thinking if going a 83-89 dropped spindle for the conversion.
I'm bumping this as I'm about to buy a 73 model to replace my crashed 79 model I have the disc brakes in my 79 and really need to know about the camber difference.
It's not the camber that I was told could be the issue, it's the caster. Camber would be way easier to fix.
