I want to change rear drum brakes to disc brakes on a 1992 honda accord lx 4dr

There's one O2 sensor located in the exhaust manifold. I am unsure if there's one in/after the catalytic converter or not

Remove the tire and the brake drum. Get a big hammer and smack it out. Put in the new one, draw it in with the lug nut. Put brake drum back on, put tire back on, fixed.

Your car has drum brakes on the rear. Did you have the parking brake engaged during the time it sat? If so the parking brake lever probably rusted in place. You might be able to loosen the cable at the drum. Otherwise, you need to remove the wheel and drum to free up the parking brake.

on the 1992 Accord you have to remove the hub and bearing assembly in order to remove the brake rotor, you will have to remove the steering knuckle in order to get access to the brake rotor.

check if theres a deep scouring on your brake discs if it does its ur bakes pads metal is getting in contact with your brake discs u need to change the pads and reface the discs to remove deep cuts on it.

Inside the trunk you will have to pull back the carpet and a the carpet material behind the tail light assembly should have nuts 2-4. once these are removed the assembly can be removed from the outside. Just turn the light socket and replace the bulb.

-very important check for brake light when pressed (outside rear)
-did u recently change any bulb at the rear if yes recheck if it the right brake light bulb 1157
u need to do a dignostic for the d4 light and it will lead u to the problem

possible bad brake light switch below the brake peddle.

is the front (in the hood)

you get all the lug nuts tight, the weight of the car on a loose lug can make that noise from the wheel, jack the car up and manually spin the tire, if you can give a more indepth description ill try to help, i have OnDemand5 if you have any other questions
