new lift bigger tires = weak braking??

i have 2011 dclb trd sport and recently went from my stock 265 65 17 to 285 70 17 and now i feel like its taking me alot longer and alot more pressure on the pedal to stop my truck...especially when i have passengers or a load in the back... any suggestions that wont cost me thousands of dollars? does trd make a better brake pad by chance? lemme know please anything will help thanks alot

 

Rear brake proportioning valve probably needs to be adjusted. How much lift do you have in the rear? I know bamf makes one but I don't know if it works with second gens although the design cant be too much different. Should run you $25

 

you can try stainless steel brake lines. that will at least make the brake pedal feel less squishy.

others can speak better to this, but i think the next step would be a better brake pad and then a higher performance rotor.

really, for the cost, just leave extra space between you and the car in front of you. after i lifted my truck, i found myself driving slower and not as worried about the increase in braking distance.

 

You can go higher perf brakes. High performance brake pads have an annoying tendency to have more squeal though.


I'm running 285/70R17 and I can pretty much lock up my 2011's brakes at will - but I'm a regular cab.

 

That's a first gen mod.

 

pads and rotors

 

If it were me, I'd start simple, bleed my brakes and make sure that's not the issue (doubtful that it is but it's the cheapest thing to try before dropping a lot of money on mods). Next, I'd try swapping to stainless steel brake lines. They seem to make a big improvement since they don't swell like the rubber hoses and force the pressure to be put to the caliper rather than lost expanding the hose. Lastly, I'd upgrade the pads and rotors.

 

yea i have been leaving TONS of room like u said...i guess it makes me a better driver thanks for the input

 

thanks for the step by step this sounds like a good route

 

Do 2nd gens not have a lspv? If so how do they differentiate braking power?

 

(lift= added weight)
+
(big tires= added weight)

= more braking force.

 

A lift alone will not affect braking force if everything else is kept stock. The components of a lift are not that heavy. Lifting may affect how easily you can control your braking though since you'll have a higher center of gravity.

 

...with rims n tires?

higher center of gravity, probably gonna feel more pitch/roll in body.

 

I was just commenting that a lift all by itself, with nothing else done to the truck will not affect braking. The pitch/roll will depend on the lift as a lot of the lifts use much stiffer coils and keep the truck flatter in corners and resist the brake induced nose dive much better than the stock coils.

Going to bigger rims and heavier tires will have a much greater impact on braking vs. just adding a lift. More rolling momentum makes it a lot harder to stop.

 

you need to upgrade your brake pads. stainless steel lines will only make your pedal feel firmer not improve braking distance.

 

Rims and tires are unsprung weight. Weight In the cab as passengers or a load in the bed would effect the rear braking.
