Big Brake Kit for 80-gauging interest**

[landcruisnman]

I’m designing a big brake set up for my 80. Using 14” rotors and wilwood 6 piston calipers. Once I get it finalized, I’ll post pics and performance feedback. Stay tuned. Pictured a set up we made for a 90’s Bronco.

Why not just go Hydro boost and save enough money for gas

 

[audi2nr]

I'd be interested, what's the minimum wheel diameter?

 

[landcruisnman]

Probably 17”. Not sure yet.

I run Tundra 14" rotors and the Wilwood 6 pistons narrow superlight 6R's up front. 18's fit and 17's will be extremely tight but haven't tried them. Wilwood states nothing less than 18" on their website but that's in reference to the kit I butchered.

Hydroboost only increases clamping power.
If the car is capable of locking the tires up then it provides no benefits as far as reduced distance or repeated braking.

Pad compound and rotor swept area are huge parts to braking.

I have a 15" kit with 6 piston wildwoods on my 4900lb truck and it stops like nothing I've ever driven

I would be interested in a plug and play kit

 

[bhsdriller]

no

That looks amazing and probably represents some hard work. The calipers and pads on these LCs are so small and wear out quickly.
What would something like that be priced at ? AND would this be for front and rear?

 

[justinlyman]

interested.

I would actually be interested in rear. Maybe once my front rotors wear I would entertain the rotors IF you can make a slightly different offset(changed to slip fit rotor design). Looking like you make the hats in house?

Here is the clearance I had when I fitted the 18's. It may be possible to squeeze another .5" of clearance there assuming your looking at the same calipers. Guessing if you don't make 17's work, you will get very little interest. This crowd likes their 17's!

If anyone is considering better brakes I would certainly take interest. These calipers aren't much bigger and are amazing, even with a tired booster I have here. If you think your brakes are fine with anything other than stock 80, your fooling yourself. If cost matters I think the calipers match well with the OEM MC/ booster in my experience with LSPV and ABS still in place.

Stay tuned.

Hydro boost works pretty amazingly well in my cruiser. I've had my trailer brakes go out on my camper on the highway mountain passes near beauna vista Colorado and it stopped very well still. I would still be interested, but only if the rotors are machineable rotors. Drilled and or slotted rotors are not. I personally would rather use toyota rotors and pads over willwood for parts availability reasons as well.

Wilwood rotors are amazingly easy to get.

Wilwood sells rotor blanks that aren't slotted.

Hydroboost does nothing but increase clamping. It's not going to add repeatedly or lower stopping distance.

I had hydroboost installed on a stingray with a built bbc that did not generate ample vacuum for booster. I thought it simply replaced the booster?

On topic: this set up looks really neat and I imagine worthwhile for people that want to use their 80 for more than leisurely strolls. Wilwood is generally quite good. I'd bet once the work is completed and a comprehensive list of parts provided, there would be very real interest. Does anyone else currently offer a complete off the shelf big brake package? I really like how the LC community is so hands on about finding ways to improve their vehicles; not simply waiting for some big company to tell them what they should buy. Awesome stuff.

It is a booster replacement and creates a firmer pedal. Especially in a situation like yours. I have it on my lightning because I make 8" of vacuum at idle .

i did this a while back. it's pretty easy to do and braking improvement is huge.
you will be happy with the upgrade.
i found 14-inch rotors require a 18-inch wheel.

Clamping force increases friction. It's a main part in the equation of coefficient of friction. I've never had issue with brake fade so far. I have had issue with not enough pedal force. I no longer have that problem. Converting to hydroboost almost doubles line pressure over vacuum boost. On hydroboost conversion kits in Australia for cruisers they give about a 40% reduction in stopping distance in testing compared to a vacuum booster. But I agree bigger brakes do aid in preventing brake fade. But I personally have not experienced brake fade on my 80 yet. Colorado has some pretty big mountain passes. And I've worked the stock rotors on those passes pulling a camper and I've not had issue with brake fade yet.

So you're telling me the stock land cruiser is incapable of locking the brakes up?

The tests I see state a test rig weight of 3790 kg's which is over 8000lbs. What f***ing land cruiser weighs 8000lbs?

They claim stock brakes stop from 100 km/h in 98 meters or 294 feet.
This is absurd as most countries require a stop distance at 100 km/h of 180 feet.

I don't doubt hydroboost adds some benefits. But a larger rotor and food compound making so much more difference.
