Brake line question

I need to replace the red brake line in the diagram. Am I going to have to have the bleed the abs module after? if so, is it safe to drive it to the shop to get it done?

 

Yes, it will need to be bled, sorry my phone tricked me, I deleted my first statement.

I'd still try to bleed it as best as you can, but air will induce itself into the accumulator for sure.

Have it prepped and dont let the master run dry to reduce the effect on the system.

 

Everywhere I search for the part number 47315 it comes up with a small brake line. The one I need is long and goes all the way across the firewall and down. hmm anyone know the right part number? 2005 4.0 4x4 dcb

 

could it be one of these?

I don't know, I think it is called brake line # 1. Seems awfully cheap for such a big line. I paid 10$ for just the small caliper line.

 

For my wife's Prius, I recently bought the hard line that goes from the block at the very front of the car, under it's length, around the gas tank, and to the first soft line next to the rear wheel - about 8 ft long with various bends. It was about $36 from the dealer (I believe on the Prius it was considered the #3).

I would just stop by a dealer parts counter with the diagram you have and ask them for the part number. At least the dealer near me gives me direct part numbers all the time knowing I'm not looking to buy from them.

 

Forgot to mention - have you considered just rolling your own with Nicopp or Cunifer lines?

 

Will it be safe to drive it to the shop after I replace and bleed the line? The shop that can bleed the abs module is about 2 miles away. I just don't want to ruin the abs pump.

 

As far as I know, you MIGHT be ok IF you can prevent the reservoir from going dry and introducing air into the ABS from that side - you can minimize fluid loss from the output by plugging it as you work. If air gets into the ABS I think you should be able to tell because the brakes will feel spongy after trying to bleed the lines. If it's spongy after attempting to bleed the lines the normal way, I wouldn't drive it until the ABS is bled.

When I did my wife's Prius, I lost a LOT of fluid because the line rusted out and blew out. The normal procedure after replacing is to bleed the lines then do a linear valve relearn (using a scan tool). For the Prius, the FSM only mentions having to do an abs bleed if the unit is replaced or the reservoir runs dry (if I recall correctly). After replacing the hard line, the brakes were fine. In my case, I wasn't worried about having to do a linear valve relearn or abs bleed because I have an Autel DS808 that is fully bidirectional and has those functions. Caveat that a Prius is a different beast when it comes to brakes because of the complexity with regenerative braking.

I have read that some are able to bleed the abs by actuating it via driving on a slippery road (dirt/snow) and slamming the brakes a few times, but I'm not sure how well that actually works.

These days, if you can stomach the price (sub $400 I think), you can get lower end scan tools that while not FULLY bidirectional, do include brake/abs bleeding functions.

If you're around NH, you can try my Autel (I have never had the need to use the function on any car yet since I'm DIY).

 

Yeah I've never let the reservoir level get low. The line I need to replace is on the output side of the ABS actuator. Fingers crossed that a conventional bleed and the dirt road trick works. If not, I may take you up on trying your Autel scan tool. I am down in Nashua, NH. Thanks.

 

Ah - if you live in Nashua, I got my wife's Prius line from Toyota of Nashua. When you buy online, they are much cheaper than over the counter - almost as cheap as other ones known for discount parts (McGregor, Conicelli, etc.), but that's ONLINE pricing/ordering.

The trick with them, as I found out by calling to see if I could get the same price over the counter, is to order it online, and when you get to the checkout, put "for pickup." I forget where you put it, but if you call them, they will tell you how. The msrp of the pipe was $50 something.
