Simple newb question, but I have a 2003 3.4L 4x4. Just had the frame replaced including all new brake lines, but the dealer quoted a ton for the brake job so I'm having somebody else do it. I'm bringing the parts and fluid though, what kind do I need to get? Just any DOT3? Synthetic? Sorry just not sure what's in there and if it can mix with synth. If he's not doing a full flush might not need too much right?
DOT 3 fluid. Synthetic would be preferred but not required. You can mix Dot 3 regular with synthetic. You just never want to mix or switch the fluid #s.
Not sure for certain if I need new ones, but the old pads wore very unevenly. I don't know if it was an issue with just one of the pins getting hung up, or if one of the pistons was seized or something, but I'm replacing them. I got centric preloaded ones.
We never recommend DOT 3.... DOT 4 or better... They make a DOT 5, it is NOT compatible... But DOT 5.2 or better is...
It comes down to boiling point. DOT 4 has a higher temp than DOT 3.... DOT 3 is for the older systems like drum brakes.
Most factory vehicles are recommending DOT 4 now.
We personally run a 600 + degree brake fluid in ALL of our vehicles... ATVs, Bikes, Trucks, and race cars. We also change it out once a year...

DOT 4 is fully compatible with DOT 3, but has a higher boiling point. Why WOULDN'T you want it?
I wouldn't go outta my way to find SB-rated motor oil for my old truck, either.
Just don't go dumping silicone DOT5 in there.
