13WL Brake Upgrade

You're a little higher than mine.

 

Thanks for reference. Going to try a hair lower. The emercency break re-set also did trick auto adjusting the parking brake. So any others....I think it was 7 clicks down 5 times in a row to reset manual adjuster.

 

Your e-brake cable looks a little loose there.

 

aint no reason to be gawkin' my flacid cable. It'll work when i need it to.

 

You were danglin’ it in our faces. I tried not to see it also, but human nature got the best of me. Next thing you know I was pinching to zoom and scrolling and oh man, back down that rabbit hole. I started googling other flaccid cables and now I just sit here with my shame.

 

Too funny

 

Has a stormtrooper tried backing your truck under a trailer?

 

TSB for the upgrade to 13WL [TSB BR004-02] shows PNs 47710-0C022 and 47720-0C022 for the OE Calipers, which, of course are discontinued. Anybody have alternate OE PNs or suitabe aftermarket calipers?

I'd prefer OE, the originals (13WE) made it to 210k in 22 years, so they can't be but so bad. I won't put those back on it though.

I'm open to something else but don't want to piecemeal too much, helps me remember what replacement parts to get... think Johnny Cash's "One Piece at a Time"

 

Powerstop kit. comes with the new calipers in red and new rotors and pads.

You provided zero details about your truck or situation, so it's really hard to help out here...

I'm finding a couple of sites showing stock of the part you entered, so it may just be reaching EOL. But the current part number for the 13WL is 47730-0C022 and 47750-0C022. If you want reman units, 47730-0C022-84 and 47750-0C022-84.

I second this.

Just installed mine two weeks ago and did a brake fluid flush. They are smooth as silk

 

I didn't go red, but I will also vote on Powerstop More Information for POWER STOP KCOE2324 (rockauto.com)

 

My ‘01 Gen 1 Tundra has weak brakes even when new brakes are installed. 4” lift, 35/12.5s, etc. Will larger 13WL fit or do I have to stick to 13WE. No real answer on this on sites, just “pick the one you want” msg”

 

Is the parking brake 100% functional and dialed in correctly? If not, that is 100% your likely issue. It is so well known, there’s an entire sticky thread dedicated to it.

 

13WL will bolt right up, mild dust shield trimming needed for the larger calipers. Clears 17” and up wheels, and most 16” factory wheels. There is a TON of info on this site about the 13WL upgrade. Not sure anything will not feel weak trying to stop those 35s though. Gonna have to go with a more aggressive pad, that means a lot more brake dust.

 

Parking brake seems to work fine. Are you suggesting PB set too tight is wearing away disks or does it affect actual braking some other way?

 

Searched “13WL” and only saw one thread that led to a good purchase choice but I’ll search again. Thanks very much for info!

 

BIGGER IS ALWAYS BETTER ...and before someone does a FTFY I'll just go ahead and add a TWSS

If your brakes were same before and after the work, there's a solid possibility upgrading to 13WL isn't going to fix your issue, caliper is potentially not your problem. (but if you do upgrade, know you need bigger pads, bigger rotors, and you'll need to trim your dust shield)

If your truck is lifted as it appears in your avatar, and you didn't also raise the height of your prop valve arm, that's problem #1. Page 2, reply #33 of that thread (link) will show you one example of moving (A) prop valve arm relocation bracket and (B) how to adjust the prop valve arm to put more brake bias to the rears. I'm not going to tag him, but one of our members in an earlier year like yours recently did this, and noted marked improvement.

If making those adjustments doesn't fix your issue, problem #2 is - quite possibly - simply that your rears aren't adjusted properly, specifically auto-adjustment of the shoes for the parking brake arm, there's a very specific spacing that a lot of people have issues with getting correct. The FSM explains this, but it's probably also in that thread.

But the tl;dr on this topic, many of us have learned together over the years:

• Good braking on these trucks mandates proper adjustment of the rears, and proper functioning of the arm; when you set your p-brake, it should be locking down the rears and auto-adjusting the arm, to the point you shouldn't be able to give gas and move the truck forward when set
• If you've lifted, and you did nothing to correct the LSPV (load sensing prop valve) armature/position, your braking will be shittier.

 

PS @RickM also see this, for what I'm saying about rear adjustment, bell crank adjustment is pretty pivotal to keeping good braking but a lot of people can't quite get it right: https://www.tundras.com/threads/rear-brake-adjustment-theory-and-practice.99575/page-2#post-3378276

 

Thanks Shifty, assuming common knowledge can backfire, this is a thread about 13WL upgrade, so...my bad. I should have given more detail.

I'm doing the 13WL upgrade on my 02 Limited, still has 13WEs and I was having a hard time finding PNs. I spent some time on the phone with John at Olathe and he got me squared away. Those fellas are awesome BTW.

I'm headed in the right direction now, trying to mentally prepare for front caliper upgrade & new brakes all-round, front wheel bearings, front upper/lower ball joints, L/R exhaust manifolds. My garage looks like a Toyota parts warehouse!

The tribal knowledge here is invaluable. I genually appreciate you.
