Hawk Performance HB302Y.700 LTS Brake Pad and ATE Type 200 DOT 4 brake fluid
 

I read on this site that these brakes
would thte front of my excursion, and the webpage says they do, so I bought them, and some ATE type 200 DOT 4 fluid and took it to a diesel mechanic today.

I know I really needed other rotors than stock, but didnt realize my stock ones were bad. They were bad enough the mechanic bought 2 new ones and other pads for 120 (the o'reillys and autozone are having price wars) and installed them parts and labor $230.

But now I have these brakes and for some reason he didnt use the brake fluid (my wife picked up the excursion and didnt ask why not)

IS there a place online where I can see all the trucks these brakes will fit?

Also will a modified 351 in my 79 f250 or a newer mustang use DOT 4 brake fluid?

Most older vehicles use DOT 3 brake fluid. I believe your year specified DOT 3. DOT 4 can be used in place of DOT 3. DOT 5 can be found on high end sports cars and dedicated race cars. You're likely fine with DOT 3.

A random pick from a Google search on DOT 3 vs 4: https://www.quora.com/What-is-the-di...-4-brake-fluid

For what it's worth, the 2017 F-350 specifies DOT 4.

Thanks. I guess that's what the mechanic meant. And I guess the brakes need high performance slotted rotors instead of the ones on sale he got-

I've never flushed my phone2006 mustang brake lines I will use the dot 4 on them

If you want a (nasty) surprise, flush the brake lines in the '79 F-250. The amount of crap you get flushed out will make you want to replace every hard brake line. My '91 Ranger had such an accumulation of what looked like rust particles that I started inspecting the brake lines to see if I could collapse them with my fingers.

I've heard that you do NOT want to put cross drilled rotors on a vehicle that is used for towing. My understanding is that the rotors develop cracks between the holes due to the added stress of towing. I read it on the Internet, so it must be true!

I haven't found the need for cross drilled or slotted rotors.

True, same principal in racing, hard braking, heat and aggressive brake pads cause cross drilled to be more prone to cracking.

Metal brake
 

Do you know if there are metal brake lines made for 79 f250 I can upgrade to?

Lines

Im sure I read here about slotted rotors going g with these hawk brakes, maybe for excursion owners that don't tow ? ( Hard to imagine)

So I can use these hawk brake pads on stock rotors?

Sorry, I have no idea. Look on parts sites like RockAuto.com or call up the parts department at your local dealership. The dealership is a long shot. Ford stopped selling a lot of parts for my '91 Ranger a few years ago. For some parts the only way to get them was from a junkyard or third party.

Now I need to.figure out if my f250 is a long bed.

Didn't the definition of long bed change throughout the years?

I always thought that on a full size pickup truck a long bed meant 8'.
