Are liquid nails and gasket sealant stronger than brake fluid pressure?

[verugador]

Long story short: I after numerous trips to autozone I could not find a caliper to fit on my 16" rotors with my 15" rims. The previous owner somehow had everything working with no obvious alterations. I chose to grind down the 16" wheel calipers so my wheels cleared them. This didn't work and I ruptured one of the crossover chambers even without taking off any more than necessary for clearance.

The real question: Is it insane to put gasket sealant and liquid nails over the hole and hope it is safe and functional or do I need to keep researching or god forbid bring it to the stealership?

Any help appreciated. What I thought was a simple swap job has turned into a nightmare.

Completely and totally insane. This has ZERO chance of working. The first time you hit the brakes it's going to blow that stuff out. You're talking about hundreds of pounds per square inch of pressure.

Seems dicey. If it did let go, well, there go your front brakes. Could be trouble for you, could be trouble for someone else too.

Was this part of a Tundra brake upgrade? I've never head of the stock calipers not fitting on 15" rims.

Pretty much what they said. Absolutely not! Aside from the pressure you would be subjecting it to, brake fluid is highly corrosive to things that aren't designed to handle it. Anything that risks your brakes you should do right.

Perhaps wheel spacers are in order, that or get a second opinion from a different parts store on the correct parts. All the Autozones around here are idiots in my experience.

Yeah it feels quite risky to me but I am unfamiliar with the physics of it all. Not a tundra swap because i didnt want to have to buy a new set of rims and wheels. I havne't had any trouble with the rotor warping and I live pretty far up in the mountains so I do a lot of braking.

Perhaps the problem lies with the duralast casting. I believe I have 16" rotors and 15" rims. The 15" calipers didnt reach the mounting bracket because the rotor was too big. And the 16" calipers were too big for the rims. I haven't heard of this happening to anyone else so I am at a loss of what to do. Might have to take it in and see if OEM parts are somehow that different than the duralast ones.

Yes, could be that you have the wrong size of rotor. I'm not sure what the 16" dimension is, but you'll want something that matches these dimensions for stock brakes:

And sounds like you're going to need at least one new caliper to go with them, especially if you're up in BC. I grew up there, no way I'd want to have any doubts about my ability to stop--the chip trucks can have those runaway lanes to themselves.

The confusing part is that whatever the previous owner had on there worked like a charm. He was a toyota technician so he probably knew a lot more about the specifics than I do. I am still trying to track down his number. I'd rather not downgrade to smaller rotors but hopefully I will know more tomorrow when the shops are open.

Got a pic? I'd say go ahead and try, it may last one pump.

Rock Auto lists different calipers for 15" and 16" wheels. Do you still have the one you took off, that was working? There should be a casting number on it somewhere that you can use to match it up.

I'm seeing two different casting numbers S12WE and S13WM.

Don't be ghetto when you're working on brakes, if you want 15" wheels, get the factory 15" brakes, they stop fine, people over-exaggerate how "bad" the brakes are on 3rd gens, my factory brakes (15") stop 35's with enough force to put my ass through the windshield.

Amen and Amen!

If you don't understand the physics of the brakes well enough to know how bad an idea patching would be, then don't mess with your brakes at all. Put the stock calipers back on there. They are perfectly functional and no need to go bigger unless you're towing, and even then, they're still serviceable.

For clarity on the castings, check out the tundra brake master thread by BFAD in the tutorial and doc reference thread (in the master thread sticky). If you haven't seen that thread yet, then don't post anything more until you have read it. It has pretty much all the info you could ever need already posted.

Just to make sure everyone's on the same page, he's not doing the Tundra brake upgrade. He's apparently dealing with a set of rotors for 16" wheels, and the truck has 15" wheels on it. Toyota changed some components in the brake system depending on what wheels the truck was coming with.

I think the flaming he's getting is based on the idea that anyone who would consider patching a caliper has NO business working on brakes at all. We all try to be helpful, but sometimes the most helpful thing we can do is recommend professional help.

A fair point. :brushteeth:

I agree... I almost shit a brick when I saw the first post.....

ound: to the title of this thread "Are liquid nails and gasket sealant stronger than brake fluid pressure?" :lol:

 

[Doc2012]

Wheel spacers are another option.

SpiderTrax all the way.

Didn't read a single post, but is the best thread title that has ever existed on any thread.

Just like me.

JB Weld is a much better option!
