I have 85 4Runner with a bad front passenger calliper and my master cylinder just looks like crap. I would like to upgrade the whole system to vented rotars and V6 callipers new bigger master cylinder the whole jazz.
I have seen a few posts of people touching on the subject in other writeups or whole builds but I was wondering if anyone has a writeup on just the brakes upgrade. I have searched it a few times but not found anything to run with. I keep getting side tracked in all the awesome threads..
Im not a full time mechanic but all the sweet info in this forum is sure turning me into one...

Thanks in advance...! you guys rock...!

I have an extra set of rotors for a IFS if you want em for cheap

Wabfab will tell you need wheel spacers

I am in the midst of putting on some V6 calipers on mine,

Brake Rotor Swap – Vented Front

Some folks like to swap out their solid rotors for vented rotors. This is a simple and somewhat inexpensive modification. I did this swap because my brakes were getting very hot and making some very annoying noises. If you can change your brakes you should not have any problem with this swap.

79-80 toyota mini axles -> Rotor bolts onto hub with 6 bolts and the wheel studs are pressed into the hub only. For Land Cruiser vented brake swap you must use 79-80 LC rotors.
81-85 toyota mini axles -> Rotor bolts onto the hub with 2 bolts and the wheel studs are prasses through the hub and is pressed into the rotor. For the Land Cruiser vented rotor swap you must use 81+ LC rotors. Uses Toyota 90942-02053, Dorman #610-264 or Napa 641-3126 wheel studs.

The Landcruiser rotors are wider because they are vented but otherwise fit right on with no other modification besides the need to run a IFS caliper.
The caliper comes in two flavors... one has two larger pistons and two smaller, and another has four pistons that are the same size. The ones with four large pistons would technically give you more braking force. I used the same pads because mine were still fairly new... so you don't need new pads unless yours are low.

 

Welcome to Yotatech.

V6 brake upgrade info is all over this forum and others. Keep searching as it's readily available.

Lots of options as to how far you upgrade.

:wabbit2:

 

The only braking that will improve is with the extra clamping.

The surface areas are the same...

So if you want "up grades" the best thing is a dual diaphragm booster, with a 1" bore, and IFS calipers.

Where you get the BEST results of this swap is going from the warping prone non-vented rotors to vented rotors that can handle more heat anyway.

 

Thanks for the info, I ordered new calipers today...

 

your going to need rotors, wheel spacers
