Question about brakes.... (3 Viewers)

[bjowett]

The stock 13.9" Tundra rotor does drop right onto the 200 spindle... the 200 and Tundra spindles are pretty much identicle, along with the hub and bearing. The 200 backing plate slightly touches the Tundra rotor, a slight tweak with my hand eliminated any interference.

ptr09-34070 should bolt onto the 200.... you will need some big wheels to clear that kit.

Just to be obsolutely 110% on this, I'll mount up one of the Tundra's calipers to the 200 spindle. I'll be ripping into my Tundra for some serious mods in the next week or so.

Ok...so we are talking the STOCK tundra brake kit vs the STOCK LC brake kit.

We are not talking about the BIG BRAKE UPGRADE kit from TRD.

From what you have seen the stock tundra brake kit is going to be considered an upgrade from the stock LC brake kit?

 

[bjowett]

Yes, it is an upgrade using stock Tundra stuff, no big expensive kits. The larger rotor can produce more brake torque (leverage) and it also has more surface area and mass to deal with the heat. I'll do the math....

Are your findings for both the front and rear rotors?

I may have to order a set of front and rear rotors and brakes form my local toyota dealer and do an upgrade.....or should I just do a brembo kit that just replaces the stock 08 tundra stuff?

EDIT....seems that the brembo kits that I am finding are only BIG BRAKE upgrade kits, so those are out. Will have to call toyota monday and find out the prices for stock tundra stuff.

 

[bjowett]

Tundra rotors retail for about $125 each, part number should be 43512-0C020. Don't forget the calipers, you can buy a used set for well under $200 at car-part.com. New price???? There are probably a dozen pad choices. Rear brakes look to be the same, but I have yet to verify this.

Eventually I will have at least one high performance rotor available in Tundra size. Might have to look into becoming a vendor over here....

Are those LC vs Tundra Rotors?

 

[bjowett]

Those are both Tundra rotors, same size.

One stock and then one brembo?

 

[bjowett]

One stock and one Jowett Engineering Prototype.

 

[dtt255]

One stock and one Jowett Engineering Prototype.

So how about a quote for 4 rotors and calipers....

 

[bjowett]

Right now I'm working on the front two piece pictured. They'll hopefully be under $1k a pair. I am also working on a single piece rotor w/ better iron alloy and curved vanes... trying to get those under $500.

These rotors will use the stock Tundra calipers, the calipers that come with these trucks are excellent 4 piston units, large, and very stiff as they're made from cast iron (better pedal). I see little benefit to changing them out for an aluminum unit. That money is better spent elsewhere.

 

[chimyz]

$1500 all around...I'm in. Keep us posted on your progress, and let us know when you have some available.

Cheers!

Well that would be for the rotors alone.....not including the calipers. We need to cal toyota tomorrow and find out the prices for those!

 

[JBHorne]

I'm interested in this as well...

I'd like to do it when I "need" to (as in, when I need to replace brake parts)

 

[hoser]

I have a pair of 2007 Tundra front brake calipers removed at 7k miles and a single brand new OEM front rotor that I'm not using. PM me if interested.

 

[JBHorne]

Jowett: So are you designing new rotors for your Tundra -- but the same factory size? How are yours better than factory? I see the venting....but what else?

 

[bjowett]

Yes, keeping the same size rotor to fit under the current wheels and calipers... I have no need for 20's. The improvements are to the venting - curved vanes instead of straight. Rotor iron alloy is upgraded. Rotors are heat treated before machining. The rotors pictured are 2 piece floating which have more benefits still. They allow the rotor disc to expand freely, weigh less, and trasfer less heat into the hub and bearing (remember we have unit bearings now).

do 200s have load sensing proportional valves (lspv)?

i drive an hdj81 which has an LSPV. i wonder if the 200s still use this technology to compensate for brakes under heavier loads? its a mechanism that increases brake pressure when it has sensed that the height of the LC lowers (due to heavier loads). If you find an LSPV under your rig, it should help. unless you modified the height of the 200 without adjusting the LSPV' height. no one has mentioned about an LSPV in this thread, so i am not sure if the 200s still use this.

 

[invisibleforms]

With the amount of weight that is being added to my 200 series I noticed that the stopping is taking just a little longer.

It was very evident last night when I went out with 4 friends in the truck and noticed that I was having to start stopping sooner.

Any thoughts on this or am I looking for excuses to keep changing this beast??

I wondered the same thing. If I were to carry 4 people with my 180lt sub tank full I think I would take longer to stop. We were going to take out the rear passenger seats to save a little weight for my next trip given they are not really viable with a full load but ran into issues with the air bag system. Before I head off again I will weigh my truck again and see where I am relative to GVWR. There is no doubt that for long range travel with added bumpers, sub tank, roof rack, sliders, drawer system etc... you will likely exceed the GVWR if you have more than two people and anything more than a light payload.
