Brake booster part number

I just got word from the alignment shop that my brake pedal was going to the floor with them and they worked on it a while and found that the MC is leaking g into the booster. I have a t100 MC already that I got off a guy in the forums who only used it for a test piece and so I've been wanting to do the t100 anyways. But I've seen a few people do a sequoia upgrade as well so which is better? I called the parts store and was going to get them to get me a T100 brake booster but they were getting a lot of different results with part numbers and I couldn't find anything saying exactly which year and features They needed to select To get the right one.

Pn 53-6401 wearever and weaver brand was one they found and pn 53-2791 was another I found. I'm in need of my truck to be running ASAP so I need to do this rather quickly if anyone can point me to the most reliable brand they know of regardless of cost. I was told the oem isn't an option anymore but idk.

 

I found a few different brands and part numbers and my 06 4wd Tundra abs would require one with abs amd 4wd I'm assuming.

 

Couple Q’s, did you see if Toyota sells it separately? Did you check to see if Advics makes a replacement booster using their part lookup tool (which is linked in Alison’s system/site)?

 

I'm not familiar with advics or Alison's what can I bought my OEM steering rack from Josh at first gen off-road I asked if he could get me a T100 booster from Toyota while he was at it and he checked on that for me and was told that it was a discontinued part. That's as far as I've went with trying to find OEM. After being given part numbers from the parts store, they inevitably told me they couldn't even get a T100 booster even though it was shown in their system. I've just ran into way too many options for me to get lucky enough to just buy one and hope it works. In my mind I would get one that was for a 4x4 with abs but then I've seen some that mentioned a VSC and I don't have a clue if my truck has VSC or not but I don't think it does. Also it seems like there are a couple different batches of year models of T100s so that's another thing that I'm not sure why certain year models would be different and which is what we can use. I don't mind using a Sequoia brake booster if it is an equivalent upgrade. I've seen the Sequoia brake booster mentioned a couple of times but nowhere near as many times as a T100 upgrade. I don't know where people get the specifics on which one to buy because I have searched this forum and Google top to bottom and have found very little information except for on one write up on this page that a guy posted the link to the one he bought on eBay but I don't really want to buy a $60 booster from eBay. I feel like that's just asking for trouble.

 

OEM = original equipment manufacturer

Denso = OEM
AISIN = OEM
Advic = OEM


There's a few others. But yea, what shifty is saying is skip the stealership and 1stgen and go straight to the source.

 

I see you have 2 trucks listed, are we talking about your 2006 Double Cab?

On your rear axle, do you have 1 soft brake line or 2? If you have 1 then you do not have VSC.

My truck is also a 2006 Double Cab with ABS and no VSC. I also had the issue with the master brake cylinder leaking into the brake booster. My truck has this weird 2 piece master cylinder and the rear portion of the master cylinder (the part that was leaking) is only only available from Toyota if you also buy the front portion of the MC and the brake booster (and is pricey so I understand why you want to change it).

Given that our DC trucks are closely related to the Sequioa, I'd be tempted to go that route instead of the T100 setup. Plus, if you do that, it may make putting a Sequoia rear axle with disc brakes on your truck easier...

 

Gotcha. I knew Denso and aisin in a lot of cases were considered OEM but I have never heard of the others being referred to as OEM. Nice to know thanks

 

I will check out that when I get home. I unloaded my truck off the trailer this morning before I went to work but now that you're asking a question like the brake line, I can't remember. It's never really been anything that I've looked at too hard. I'm tempted to go the Sequoia route because I'm really considering getting a sequoia rear axle for the disc brakes if I don't wind up having a custom rear axle made but I'm not sure which Master cylinders are compatible with which brake boosters. I've put the question out a few times in a few different threads but it seems like nobody knows the answer if I can use a tundra master cylinder on a Sequoia brake booster or if I need the Sequoia master cylinder as well. I've heard some people say the brake booster is the only thing that's an upgrade and don't worry about using any of the other components but I think they were mostly referring to the calipers and not the master cylinder. I would assume the master cylinder would need to have the matching brake booster but maybe the master cylinders are all close enough that they all interchange. And yes we are talking about my 06 double cab. The 2000 AC is out of commission for the moment. Kid pulled out in front of me and I hit him but my aftermarket bumper saved everything except it buckled the frame a tiny bit and I have a new frame and I'm going to swap everything over but while I'm at the trouble of doing that I'm just going to do a straight axle front end so that I can run some 38s and put a flatbed on that sucker. I owned that truck from the time I was 16 years old. I bought it with 60,000 miles in 2003 as my first vehicle and my dad and Papaw paid for half of it for me and I paid for the other half so it has some sentimental value and I'll never get rid of it just because I don't want to. Was the best truck I ever had. A lot of memories in that thing.

 

If you are thinking about getting the Sequoia rear axle for the disc brakes, then get the Sequoia Master Cylinder as well. I've read that the Sequoia master cylinder, while not required if installing the Sequoia rear axle, creates a better, firmer brake pedal. That, and there's no point in having a mix of Tundra and Sequoia parts if moving your rear axle to a Sequoia rear disc axle.

Point being, if you are thinking about that rear axle, which requires messing with your brakes, and you already have a brake issue, now is the perfect time to swap everything over.

 

Yeah I'm heavily thinking about just getting a sequoia rear axle for the ease of just swapping everything out but I'm also contemplating saving my money and getting a custom axle made that is full float with disc brakes also. It's not that I don't think the factory axles are plenty strong for what I use on average but I am carrying a good bit of weight in my truck a lot of the time and a couple times a year I do take my truck on a road trip and I try to hit some trails with that good bit of weight. I also semi-regularly tow our excavator and skid steer which one machine on my trailer is about 12,000 lb and I try to put most of the load on the trailer but I usually pull the machine up until I get a good bit of squat so that I have sufficient tongue weight and with all the added heavier duty leaf springs it takes more tongue weight to make the truck squat then a normal factory leaf pack would. Whenever I do get my rear axle swapped out whichever it may be, I'm getting a locker and a regear and whatever it is, I just really want disc brakes mostly for the ease of maintenance and I feel like they will grab better under my heavy towing loads. I'm just really tired of dealing with inferior drum brakes on this truck. It's been a long time since I've felt like my rear brakes did anything at all. If I have to get on my brakes very hard at all it just locks the front tires up. And now that my brake booster is out, I can still stop and drive it daily but the brakes are not very good. I adjusted my proportioning valve as far out as it would go and I put the bottom bolt hole of the valve in the top hole of the mounting bracket on the axle to try and get all the leverage I can on that rod as a temporary solution but I haven't driven enough to really know if that's helping the rear brakes grab any better. My plan is to put a Wilwood manual valve on whenever I do my brake booster.
