Brake hose question

[Mechanic77]

I just bought a stainless braided brake hose kit for my truck and it has -3AN hose on it...my question is, is there going to be an issue with them being so small? I can honestly say I've never seen such small brake hoses, but I'm not sure whether or not it will affect the performance of the brakes. I realize it shouldn't have any affect on the pressure in the system, but I'm concerned that it might affect the volume/flow of fluid through the system maybe slowing the apply of the brakes....I don't know maybe someone smarter than me can chime in.

Thanks, Andy

I got SS hoses from summit, I don't remember the brand, but they work fine. I think the rubber ones look bigger because the outer rubber covering is so much thicker.

Yeah, I think they'll work fine....but I've seen the inside of rubber brake lines, and they are a lot bigger i.d. than these lines I picked up. I think I'm just going to try them and if they seem to be an issue, I'll just upgrade to -4AN hoses down the road

There is very, very little movement of fluid in your brake system. The pads and shoes are virtually right against the rotors and drums. It takes a tiny amount of fluid movement to apply them together. You're gonna be fine for sure.

Your #3 hoses are fine. The I.D. of the hose is the same as the I.D. of the hose.
