Just to join the crowd and put some skin in the game. My 80 series New slotted dimpled front rear rotors, new calipers, Stainless Brake hoses, new master clyinder and dot 4 hi temp build. My brakes on my 94 80 series are better than they where and no where as goos as my 100 brakes same graded rotors, pads, calipers, and dot 4 fluid. I say this good feeling pedal to start and slows down, but step more into it and like getting against a wall not much more braking is happening. 30 MPH stop dry payment can't lock the tires up and get into ABS. So loaded truck makes my a little nervous hi way speeds, slows down fine, but panic stop not happing. Researched big brakes, the that's a rabbit hole to thrown money off in... Front and Rear really narrows options. Wheel size comes into play now. Ceika has kits front and rear for 17 inch wheels and keep OE E brake. ok.. not great reviews on the company. Power Brake yeah for serious coin for the front only! 3400-4400 depending on 16 or 17 inch wheels. Mud member doing he own machining work on Hats and Caliper brackets and use Wilwood mater cylinders and rotors. ok he doesn't do the machining any longer. Another company slip over hub optional rotors on wildwood calipers front and rear over 8000 bucks. yikes
So chasing brake booster options, Dual vacuum one will not fit 1FZ LHD 80 series, ok, now Hydro Boost, have put together your own, Marks quoted me 1477.96 shipped AUS.. Yikes! Sweeting has a new booster with mount 500.00 plus 350-450 hoses... and 90 days to ship product,
1990-1997 80 Series Land Cruiser Hydroboost kit - https://powertrain-integration.com/products/1990-1997-80-series-land-cruiser-hydroboost-kit, this guy has the firewall adapter and OE mater cylinder adapter to use your own 1 inch master clyinder and has a connecting Pin to brake pedal for 159.00 plus a booster, he recommends 05-10 Super Duty Ford 250-350. I bought a Morotcraft Ford New for 185.00 and has the Master clyinder push rod that he claims not all new units come with, so he recommends USED ones. This is the best value for the bucks paid. I ordered two fittings and 1 I may not need from Amazon and a Hose kit from Ebay to fit the Ford Booster. it could for more than that one for 60 bucks. I could throw the hose away and buy new 1000-3000 lbs hose and be ahead just to get the fittings in steel to connect to the Booster and Hose AN 6 fittings tight 90's. Booster arrived today, Here is the Ford Part number... in the Picture. once fittings and hoses arrive I will post the progress of the install.
I going to try the Hydro booster 1st. I have driven a lot of trucks with them. They give good assistance on pedal application. It could be my 80 has a bad booster, why it feels after applying the brake initially it get hard like a wall and this will cure it. It sure can't hurt! I am trying to keep my ABS system in tact, because it works and I have a good pedal feel initially. No sponge to speak of. Bleeding the brakes was a pain to get the sponge out, it took ABS activation to help that.
This is a rabbit hole and can't dump a lot of money into very quickly. I have new 17 inch wheels now and really do not want to change wheels and tires !
Ceika big brakes looks promising, but not if they are not any good. IF the booster doesn't solve the brake problem right off, I will engineer my own brakes and utilize Wildwood parts. a member shared a drawing that maybe I can create a CNC file to have my friend make me the parts on his CNC machine. So a work in progress let's say. For those that are interested the Ford Booster new price is good, the 159.00 price is good, just have to deal with the hydraulic hoses...
take care
My last 5 days research... enjoy
