Hi guys, just wondering if excessively worn brake discs on all 4 sides far beyond service limits would result in excessive brake pedal travel?

any help folks?

How excessive is the wear and pedal travel?

It's probably contributing to it. Replace your rotors. Also, flushing/bleeding your brake fluid would likely help a lot.

soft pedal and exessive pedal travel are not the same thing.
softness is usually related to brake fluid issues (old, overheated, air).
pedal travel might be done pads or disks - but i wonder how much more pedla travel this can cause - my guess is not very much.

Would u say bubbles stuck in the abs module might be a factor? If so how would I be getting these out?

I've bled my fluid at a shop which uses a vacuum bleeder so I'm ruling out a poor bleeding. Fluid is new too. The discs thicknesses I have are thinner than the specs stamped on the back of the discs ie 10mm in the case of the rear rotor so I'm wondering if the thin discs have contributed in a lower biting point in my pedal play

so what's the problem?
increased pedal travel/low biting point?

i think worn pads won't affect this too much.
but maybe i'm wrong.

parhaps just try a set of new pads - OEM's front+rear cost just 100$.

i don't see how a worn disc could make your pedal travel more. the pistons do not retract as the pedal goes up, so the next pedal stroke should already start with the pistons in position. there are 5 things i can think of that could have the same symptoms:

1. your disc could be warped, and thus pushing back the pistons while spinning. but i would figure you could feel that when braking.
2. your wheel bearings are loose, also having an effect like #1. again, i would figure you could feel this.
3. maybe your disc doesn't have as much friction anymore, forcing you to push harder, and thus appear to require more travel.
4. your pads are soft. this would definitely have the same symptom.
5. air in your lines. or old fluid.

anyway, i don't trust those vacuum bleeders. try doing it the manual way--have a buddy stomp on the gas pedal hard while you control the valve. i think this actually forces more fluid harder than the vacuum method could.

my bet is on #4 or #5.

start by changing the discs they are shot anyways

after you change the brake fluid allow 2-3 weeks to bleed themselves ,
after this period you will have a stiffer pedal
I had the same problem
