A technical question about brakes

I have a 2009 access cab 2.7 with a 5 speed.
I replaced the stock 15" wheels with TPMS with some larger 17" wheels and tires without TPMS.
I took out the instrument cluster and placed some black tape over the TPMS light. Under the face. So it looks perfect with no light shown.

Since then I've had an occasional issue with a soft pedal.
I've replaced the master cylinder and most of the brake components as well as bled the system several times. Two different ways.
The soft pedal comes and goes. It has never gone away. There are no leaks. I never need to ad fluid and there are no others codes or lights.
The booster has tested good and so does the master. (The old one was probably also fine)
My technical question is:
Can a TPMS code cause an issue in the ABS system? Does the ABS system operate by reading the TPMS data as well as wheel speed?
This has been an issue since I installed those larger wheels. And I'm at a loss to figure it out.
Thank you.

 

The TPMS and ABS are totaly separate systems, a TPMS fault will not affect ABS or brake operation.

First off make sure your rear brakes are adjusted correctly.

Do you get an ABS, Brake, or Traction warning light when it happens?

Another possibility is that one of the dump valves is sticking or leaking in the ABS unit, don't see it very often but it's a possibility.

 

Could be that the new wheels and tires are significantly heavier and it just feels soft because there’s more inertia for this brakes to overcome. Notice this myself when I swap from my 32” P-load Blizzaks to the 33” E-load ST Maxx every spring.

 

You increased your rotational mass. The brakes are just not strong enough now possibly. Also I'd have a brake shop professionally flush your system and buy high quality and high temp synthetic fluid.

 

TPMS has NOTHING to do with a soft pedal.

Did you bleed the ABS pump separately, and BEFORE you started bleeding the rest of the system?

 

I agree with Steve. A 2" increase in wheel diameter along with tires will increase the amount of force it takes to stop said wheel. The weight will compound that.
