i always wanted to upgrade the brakes on it, the opportunity came to get a set of disc of a tundra and calipers, never seen it done on a 1994 4runner, so,
well, this is what i did,
first removed the whole assembly out to start checking how to fit it, and see what the differences in sizes

few pics for comparing (ish) the size of calipers, and disc.




calipers bolt pattern dont match



the disc its touching too much the dust shield,so need to trim it (about 10mm around) and i will shave behind the hub, to leave it level to the back of the wheel studs

 

drilled holes to fit it like the factory discs



brackets made



and fitted



sorry, not the best pic

 

then, the end, on 16s, nissan patrol wheels, not sure if 15s will fit, still some space around the caliper and wheel


now, wait till i got the paint job finish to fit it all with some 305/70r16 tyres

 

i will fit 30mm spacers, to avoid the tyres rub

 

Just what difference in pounds per square inch with the brake upgrade compared to stock ??

In the applied braking pressure ??

overall increase is pad area ??

 

im sorry about my ignorance, but i dont know how many pounds difference,
all i know its by being bigger disc/calipers= bigger pad area,
im lucky that someone put already 1inch bore master cylinder,
so definitely it will be an improvement on my old rubbish braking power.

 

Interesting how new brake parts work better then old worn out brake parts!!

I got the same improvement just by putting all new stock parts on funny how that works.

 

if you say that because you think its for the one in the pic,you wrong, that's the one im using to check if all fits,
the one its going for, cant be stopped for too long due it still on service

 

Do you have a better picture of the bracket mounted, with and without the caliper?

While looking at various other brake upgrade threads (or maybe it was the widening a SFA with IFS parts thread) there was some discussion of people not trusting an add-on bracket for the caliper mounts (I'm not sure that I completely understand their concern) but are you worried about that bracket failing?

I like the idea though.

 

I was not going from your project at all .

The bottom line as long as your happy that is all that matters

Besides if I wanted to make fun of you I could do much better with my 5th grade education !!

 

all good,

 

im open to new/better ideas,

i asked several engineers, some said to weld it in position, some told me to leave it like this, yes, i will take some more pics, thanks.

 

here they are, more pics.
