Would anyone know how to tell which brake line is the correct one to replace? Went to replace the calipers and brake hoses on all the wheels and the front passenger side brake line ended up rounding of when I went to break it loose. I think its 4731848040 but there's 2 different versions of the part and I want to make sure its the right one before buying. The other versions are 4731848020 and 4731848080.

 

My suggestion would be to go to local Lexus Parts or go to online Lexus parts retailers like Butler Lexus of Arizona or Lexus of Atlanta. Go to parts and rill down to model year and remember to put in your vin. [take the vin to the dealer in person if you chose to go that way].

Already tried looking around online for the part but a lot of the places don't really have a description beyond the years they would fit since it doesn't look to be in stock anywhere. Probably will have to try the in person route thanks for the confirmation.

 

Just call the parts department, and all you will need is the vin and some description like "hard line from right wheel area to the ABS" or what ever. Let them earn their living too. Replies you gather over the net would be well meaning but the fitment risk will be there.

regrettably your only convenient option is Lexus for dedicated parts. For on line, again use your VIN to confirm part number.

The other route would be salvage yards. But depending on where you are, the opportunity can be low or worse if you are in rust belt, the condition might be poor.

You didn't mention any of the car specifics but looking at the dealer web page for my 1999 AWD almost none of those parts are available.
If you can't buy a replacement you can probably just get a brake line flaring tool and fix the old one.
