So my 1996 4runner braking issues continue. I did a 199mm front brake caliper/ disc setup back in september. Wow what a difference!. Well, it did not last long. Front end shakes when braking have returned.
After looking over the the front end for worn parts in the steering and suspension. We came up with the fact the rear brakes are leaking fluid as the culprit. Since the rear brakes aren't doing any work and caused front to heat up so bad I may have warped the discs again.
I ordered new rear brake cylinders from toyota and new pads. can't wait for this project. Thankfully, the weather is improving

EDIT: I guess I might be wrong about whats leaking back there Just read that rear axle seals fail often great.....

 

Yes, the rear axle seals failing is a common problem on the third generation 4Runner, but you should be able to tell the difference between axle grease and brake fluid. The grease that you'll see if the axle seal is leaking is grey/black and thicker than brake fluid. Brake fluid is golden colored and thinner than the axle grease. With a quick check, you should be able to tell whether it's the brake system or something else leaking back there.

 

I had that problem when my LSPV (load sensing proportioning valve) went out.

 

The two fluids smell so different you should be able to tell just from the smell.

Are you needing to replace brake fluid ??
