2nd gen brake bleed question

I'm looking to extend my rear brake lines to compensate for a lift i will be putting in soon. I did my research on how to bleed the rear brakes...this will be my first time doing it. However now i am reading something about bleeding the LSPV? Need some insight on that i tried search engines and forums with no luck. Does my truck (2014 4x4) even have that? Or is that for older models? And if so, does it have a bleed valve just like the rest? And if i am only bleeding the rear, would i bleed the LSPV before or after i bleed the two rear brakes? Any pics or threads i may have missed would be appreciated. I mostly read this for 1st gens i haven't really seen anything for late 2nd get models?

There is no LPSV on the new trucks. To bleed the brakes, just have a buddy pump the pedal several times and start with the wheel furthest away from the MC (rear passenger) and open the bleeder until pressure starts to disspiate, then close the bleeder valve. Have the brakes re-pumped and go to the rear driver, then work your way up to the front passenger, and finally front driver. Catch the fluid in a can and make sure to wash any you spill as it will eat any paint it contacts.

 

Thanks for the help. I was also wondering what position the key needs to be in during the process? I've read on some threats that the key needs to be in the on position during the process? I think this has something to do with the VSC?

 

It should be in the "on" position. this will allow the brake booster to ensure the lines are fully pressed up. Not sure which model tacoma you have but the offroad have a hydraulic brake booster that need the keys to on. The vacuum boost models are a little different but key should still be set to the on position.

 

I have a 2014 sport, thanks for the help!

 

Instead of starting another thread I'll add a question to this one, op hope that's ok? I just bled the brakes today and only got a few ounces of old fluid out. I bought 3 bottles of toyota fluid thinking I'd use at least 2, but i only ended up using about 3/4 of 1 bottle. Did I do something wrong? Do I need to spend more time draining fluid at each wheel?

I let each wheel drain until there were no bubbles, and went from assented rear/driver rear / pass front and ended at drivers front.

 

Is it ok to use a vacuum hand pump over bleeder as long as key is on or do I need someone to press the pedal?

 

There are two reasons to bleed.

(1) get rid of bubbles after doing some sort of maintenance that introduced them, such as replacing a caliper, master cylinder, or a brake line.

(2) replace the fluid. Here you want to pump/bleed until the fluid that comes out at the wheel is completely clear and looks new, where the old fluid will usually look a little cloudy or dirty.

(2) is an inexact science. The brake system doesn't hold a bunch of fluid, but 3/4 might not be enough depending on what a "bottle" is. IE I have bought 32 fl oz "bottles" and no brake system holds that, toyota-wise. An 8 oz bottle won't be near enough to really flush.

 

When I bled mine I didn't use that much fluid either. As long as you don't have any more bubbles when you bleed the brakes you are fine. I also did a couple more bleed cycles even after I saw no more bubbles just to be sure. When all was done I made sure I pumped my brakes till they were at normal firmness before I started he vehicle again..I had no problems and did not notice my brake pedal feeling squishy or less firm like others have mentioned in other threads. Hope this helps
