This is my daily driver, so I just want to make sure I got everything I need to do this brake job instead of wasting the time pulling off all 4 wheels and finding out something like the caliper fastener is a metric hex (I don't have any metric allen wrenches).

My first question is what type of fastener holds on the caliper (bolt, hex, etc.) and what size is it (if nothing else, is it standard or metric?)

My second question... it appears that all 4 calipers just 1 piston calipers just from looking at them through the wheel, is the correct? (I only got a 1 piston brake spreader is why I ask.)

 

bolts, metric, one piston

All the bolts you'll be removing are hex; Hondas use 8, 10, 12, 14, 17, 19, 32, 36mm sizes (JIS) from the factory - you won't find any other sizes on the car unless someone has messed with it. The bolts that hold the caliper on are 14mm I think (can anyone else confirm?). The screws that hold the rotor to the hub are #3 Phillips (a manual impact driver is the easiest way to remove those).

They are all single-piston floating calipers. Keep in mind that the rear caliper pistons do not get pressed back in like the fronts do - they must be turned like a screw.

So all i'll just need a 14mm allen wrench for all 4 calipers then?

Did not know that. What do you use to turn the pistons back in?

not allen wrenches, just wrenches or sockets are fine.
Impact screw driver and probably a C-clamp to push front pistons back in. Rears are screw in.

Alright, sweet sounds like I already got everything I need then

I just did mine (98 EX) and the caliper mounting bolts were 17mm (80% positive). I replaced the rotor retaining screws too... cause they were such a PTA to remove and my impact screwdriver got in there pretty deep.

There are 2 Bolts for each Caliper that secure it to the Knuckle (Front) and Spindle (Rear). There are also 2 Bolts for each Caliper that secure the Caliper Body to the Caliper Bracket (actually, they are attached to the Caliper Pins, which is part of the Caliper Bracket). All of these bolts have Hexagonal Heads, but are not "Hex" Bolts (you don't need an Allen Wrench/Hex Key).

The Rear Caliper-to-Spindle Bolts are 14mm. Some cars will have Flange bolts (a washer-like tapering) and others employ a locking washer (10mm). The Rear Caliper Body-to-Bracket Bolts are 12mm.

Make that 100% positive... 17mm. The Front Caliper Body-to-Bracket bolts are 12mm, just like the Rears.

Definitely get a good Torque Wrench (the Click-types work great). You should also get at least a Haynes Manual , or get the Helm Inc. Service Manual . They'll have all the diagrams and torque specs you'll need.

For the Fronts, you can use your Playstation-Strengthened Thumbs. If you cannot do it with your bare hands, you need to spend more time playing video games.

But get a manual... Too many Torque Specs to list... GL!!

I was just looking through the haynes manual and it says that the caliper mounting bracket bolts in the front need to be torque'd to 80 ft/lbs of torque... Is that correct, the little 12mm need to be torque'd to a massive 80 ft/lbs (sounds like a lot for those bolts)?

 

The Caliper Pin Bolts (12mm) are 25 ft-lbs...
The Caliper Mounting Bracket Bolts (17mm) are 80 ft-lbs...

Hope that helps!
