Sorry for no pictures couldn't get under my car due to snow on the ground ATM.

1998 Honda Accord EX

What could be causing this problem, Recently when I drive one of my rear wheels are making a grinding/Squeecking noise. Beofore this happened about a week every time I hit the breaks the "Brake Lamp" on the dash would light.

Now also whenever I drive and I floor it my E-brake light comes on as well occasionally until I come to a stop.

Would it possibly be the rear brake caliper.

 

Sounds like the pads are worn down to the point of making a noise.......and worn so far that the brake fluid level in the master cyl is low enough for the warning light to come on.

Just a guess.

 

you have disc brake brakes in the rear since it's an ex. anyway get yourself a cube (i'll post pics later) to compress the rear caliper piston, When that's done install new pads.

 

I have bought/Converted my brakes to 5 bolt pattern last year and put new brake(bigger) pads, rotors, lines, etc(all brake parts where switching within the past 2 years), would I still need to switch the rotors/pads to stop the grinding or if after switching the caliper should it disappear?

 

time or years since you did the brakes wouldn't matter to much, It is the miles you put on the brakes in the 2 years and what type of driving you do that affects brake wear. On average most front brakes are replaced 30k or so and rears soonto follow around 40k but like I said it depends and on your driving habits etc. Just pull the wheels and check you pad wear and check the master cylinder to see your brake level. If the fluid is low don't add because the fluid indicates your wear and if you have to replace something and add to much fluid and go to squeeze the fluid back you'll overflow the master.

 

My rotors dont seem to be affected they are still in decent shape.I don't do much driving, I got the car last febuary , started driving it in around april(Bought it from someone who used it as a summer car) put about 10k on them and this just happened to the rear one.... Its a lowered car if that makes a difference but the other day I hit a big bump and the noise went away then came on again a couple minutes later after hitting the break a couple of times... My mechanic is trying to tell me to switch everything but I think he just wants my money.

 

I know it is cold outside.....pull the dang wheels and inspect all four brakes......did you open the hood and at least look at the fluid level in the master?
