Hi..I have a 99 Honda Civic LX and I am having a problem with vibration on brake pedal. What causes this?

 

does the steering wheel vibrate when u hit the brakes?

 

no steering wheel does not vibrate

X2, old rotors warp and get mis-shaped. OEM rotors or even aftermarket blanks are about $ 30-50 a piece, and can be installed fairly easily with the right tools.

 

I don't have rotors on the back...my car has drums. Can you resurface the drums??

no, not that im aware of. You can have the components in them replaced tho.

this ought to help.

Is it safe to block the brake fluid line with pliers and see which drum/rotor is causing the vibration?? One wheel at a time of course

umm... no
As a matter of doing just a general tune up, you should have them both looked at by a pro or shop before you start doing things that may make things worse. Its just wiser to have them both replaced/fixed at a shop if you are unsure of what you are doing.

 

Well..this is the thing. I had two lower rear trailing arm bushings replaced last week and they took off the rear drums because the mechanic said they needed more room to work. Now when I press the brake pedal there is vibration.. I talked to the mechanic and they looked at the drums and they cleaned them but still there is vibration. wtf could it be??? They said I need to bring the car in and they will block the brake lines and see which drum is causing the vibration..Is this gone cause any damage to my car??? Should I take it to a differnet shop?? I had no vibration before they took off the drums.

Let <U>them</U> do it if they messed it up, dont go messing up your own car if you dont know what you are doing. The shop caused the problem, let them fix it, they are the ones that have to be concerned the most here, not you, they are obligated by laws of conduct to repair any damages they have caused while doing repairs to other parts on your car, or else risk facing a lawsuit.

 

What should I do/say if they say there is nothing else they can do or refuse to fix it?.What should I say if they say that the vibration might of been there before they removed the drums (which is not true)??

 

if its just the brake pedal pulsating and not the steering wheel its going to be in the rear (seems you know that but figured i would point it out)

you CAN safely clamp the flex hoses in the rear one at a time to determine what side is causing the issue, but i would just have both sides RESURFACED, yes, drums can be resurfaced.

chances are when they removed the drums they didnt index (mark) exactly how they were mounted on the hub, and they were put back on in a differant position, which wouldnt cause a problem normally, but chances are you have some rust buildup on the inside hat of the drum and on the surface of the hub. cleaning both surfaces and resurfacing the drum and adjusting the brake shoes should resolve the problem. no big deal, no harm is being done, just wasted time having to go back to the shop while its fixed.

Replacement of the shoes is also a very smart idea if you resurface the drums, otherwise the shoes will grab the new drum unevenly.

@ the OP:

Have you pulled up on the ebrake and felt it pulsate through the cables?

The replacement of those two bushings could have cause the toe to go out of spec in the back, since it is controlled by those two arms. If they loosened the compensator arms or removed the whole arm, you will need a rear end alignment. Sometimes so much as putting a new bushing in there can throw off the alignment.

Might want to observe your tire tread wear patterns to help pinpoint an alignment issue.

 

yes you can resurface drums, but sometimes it easier to replace them

 

Why should I pay to replace them when the shop messed them up...so they should fix them or replace them
