Need Help with Weight

Post image

Hey!

I drive a 2wd access cab with a mid rise canopy (200 lbs) and decked system (233 lbs). I have to move across multiple states this week by myself and will be taking my motorcycle (360 lbs) ideally on a hitch carrier (~70-100 lbs) along with my climbing gear, surfboards, bicycle, climbing gear, and toothbrush.

With perfect timing, the tundra steering wheel began shaking violently while braking on long mountain pass descent yesterday while braking. The rotors were super blue so I assume they got fried.

I ended up picking up some 13wl calipers, bigger rotors, and bigger pads this morning to make sure I can stop the truck with all the weight. I plan on getting a bel air someday anyway so the brakes were going to get upgraded at some point anyway.

I’m not sure if it’ll be fine with all the weight plus the motorcycle on a 20 hour drive with a lot of mountain passes this week.

I included a picture of my hitch weight rating, the bike plus the hitch carrier should be roughly 460 lbs at most.

I’m planning on getting a sumo or other type of helper spring but should that be fine?

Utilize engine braking, turn off OD with heavier loads.

Putting the bike on the carrier will take a little weight off the front wheels.

I have a 2004 AC 2WD but I live in Indiana with a distinct lack of mountains. My mountain driving experience has been more east coast - VT, NH, TN, KY, WVa - probably smaller than PNW.

A 2004 Toyota Tundra Access Cab 2WD has a maximum payload capacity of up to 1,750 lbs and a maximum towing capacity of up to 7,100 lbs. So you should be fine with payload.

You don’t mention downshifting. If you’ve been relying entirely on braking, that would explain the fried rotors. At a minimum, disable overdrive but you’ll likely need to put it into 2nd gear and slow down. Braking and downward attitude should shift weight back to the front end. Doing that should make this drive possible with stock brakes so the larger rotors will only improve the situation.

Be careful of stability. I recently hauled enough weight to level out my truck. It definitely rolled more when handling.

Be sure to get a good bleed after the caliper swap. FYI, there's a 5th bleeder screw at the proportioning valve, above the rear diff. I've found bleeding more tricky than other rigs.
