more AllanD dual piston brake upgrade info not in the library

[rickcdewitt]

i noticed theres nothing about this in the library and figured it should be with the rest of allens brake info

1995-1997 on Rangers ONLY.

If you want them to be easy to connect on an '89-94 (and some late 1988's)
you need to order a NON-ABS Brake hose for the drivers side from a 1997.

1997 was the ONLY year that ford made any Non-ABS two piston trucks
(I have no idea why)

If you are retrofitting a two-piston brake D35 TTB onto an earlier
RBV (Gen1 Ranger/Bronco2) you specifically want the ABS style brake hoses.

The '89-94's without ABS use the frame end of the drivers side brake hose
as a T-block to split the brake line off the master cylinder to the left and
right side brakes (Thus the NON ABS hose)
If on the other hand you have an ABS equipped '93-94 you want the
ABS hoses. (Duh!)

RBV's '83-88 (except for some late '88's) have a seperate T-block mounted
to the frame that divides the brake line and a short line that runs from the
block to the drivers side hose. so the 95-97 ABS hose will work fine.

That's a good idea. That's a question that pops up quite often.

I am planning to do the swap sometime soon, given things work out. I could probably offer pictures

Sorry guys, I can't help but know this stuff but it only pops out when someone asks the right question....

This is no help to me ;-). I already have aftermarket longer stainless hoses and they are marketed for a '83-'97 Ranger.

 

[AllanD]

that's because most aftermarket hoses lack a rigid tube section.

And what is different between the various calipers is the rigid section
of the line to specifically accomodate those different calipers.

Maybe the effects of the swap......

Bolt on caliper. Makes the steering knuckle a non-wear item.

More consistant braking.

Calipers are the same as used on new Rangers, meaning lots of availability.

Not sure what else to add.

I did notice that the "sticky" for brake upgrades said you need different rotors. My local parts store offers the same rotor for my 93 and a 97 non-abs Ranger. This is correct right?

 

[mjonesjr]

the '93 and '97 non ABS uses the same rotors; I installed new '93 rotors on my '97 when I had it. The '97 I had didn't have ABS on the front.

 

[AllanD]

The "late" rotors will certainly fit onto the early truck.

It's even possible the aftermarket suppliers "cheaped out"
and stopped making the early style D35 rotors, but when
I first looked into doing this swap I examined everything
VERY carefully specifically looking for differences...

what I found was that relative to the wheel bearings the friction
disc as moved outwards 8-10mm.

the difference is enough to allow a 1990-94 to "spit" the inboard pad
after only slight wear if someone ignorant of the difference accidentially
installs a 95-97 rotor onto a 1990-94 vehicle.

The reason for this was revealed when I tried to install a 1993 rotor
(from my explorer engine donor) onto the 1996 Ranger beam I was
using and discovered that the back friction surface of the rotor was
in hard contact with the heads of the caliper bracket bolts.

Most parts listings I've seen show different rotors (both ABS and Non-ABS)
for the 1995-97 Vs the 1990-94

FWIW BOTH my 1993 Explorer "organ donor" and the 1996 D35 Ranger axle
were ABS equipped.


So I'll say "ya need different rotors" until proven otherwise beyond all doubt
I won't be holding my breath waiting to be proven wrong.

Generally speaking if I find a parts listing that disagrees with what I know
I usually dispute that parts listing. I've seen it enough times to know
that the paper just lies there and lets some idiot print any combination
of symbols and pictures on it witout complaint.

For example, how many here have been asked "what axle ratio" when
buying brake parts for a 1991-97 Ranger? answered 3.45 THEN been
given the WRONG parts.

Ditto for telling the parts counterman that you have an 8.8" axle
when buying outer axle bearings...

Or asking for a pilot bearing for a 1988-up 4cyl (or for any year 3.0 engine or 4.0 engine)
and being asked Mazda or Mitsubishi trans?

Yes the pilot bearing is different, but that's not the point, the point is
that '88-up the Mitsubishi trans was 2.9 engine ONLY.
2.3, 3.0 & 4.0 were Mazda only.

better to let you grub around on your truck for us than have more "how do i?" or "what do i use" questions.we need more info and stickies.

not 10 q's everytime somebody reads an upgrade in the library.

 

[Bryan22]

What allen said answered another question I had when first owning my ranger and being asked if my 3.0 had a mitsu or mazda trans. My question was what kind of lube goes in the tranny, the answer any 88 and up non 2.9 uses ATF. is this correct?
