2003 Toyota Solara Q&A
2003 Toyota Solara Question: Can catalytic converter cause car to lose power, shake, and make brakes hard?
Have the brakes checked to see if they are still applied without pushing pedel, ASAP. Possible fire danger if the brakes get hot enough!! Possible brake booster, master cyl.etc! - pushrod
A restricted or plugged cat can cause loss of power. Don't forget you still have a downstream cat and a muffler that could plug up. This should not be a problem with an experienced PAT(PROFESSIONAL AUTO TECH) to diagnose it. - PARTS GUY
you likely have contaminated brake fluid(power steering fluid) is what we see most. take the master cylinder cap off , flip upside down , look at the rubber - if swelling the you got problems. at a minimum m/cyl , front brake lines and front calipers w/ a flush. anything the power steering fluid touches (petroleum based) will stick and swell. and the answer is no , you cannot flush it out and and be done with it as it sticks to rubber. - cntsmith
