Ok here's the situation...

My steering wheel really shakes when I brake at speeds over 75km/h.

Now before everyone says rotors, the day before I changed the pads braking was pristine! I get the pads changed and the mechanic reminds me to take it easy on the brakes for a while and I do just that. Two days go by of really mild city driving and no hard braking at all till I get on the highway going about 110km/h and I need to brake just to bring my speed down about to 95km/h and the steering wheel shakes.

So immediatly I think that I got warped rotors. I decide to get my wheels balanced and bolted on correctly and I check again... same thing.

So like a good boy I log onto H-T and do my searches, do the reading, and I get all kind of answers from warped rotors to hot spots to bad wheel bearings. I also read the StopTech article about the myth of warped rotors. So now I'm really puzzled.

Anyone care to give me any insight before I go to my mechanic tomorrow morning?

Aftermarket replacment is not an option, no money.

Does it shake while you are driving fast on the freeway and not on the brakes? You might need an alignment.

 

no shake when driving.

 

Lug nuts on tight enough?

 

maybe he turned your rotors and warped them? i used to work at a brake place and i have done it before. the thinner they get the easier they are to warp. you can also **** them up from heavy braking or riding your brakes hard where the rotors are excessivly hot

I thought of that, so I got my wheels balanced and tightened properly just in case. Problem continues.

Turned my rotors? I've never heard that expression before. Please explain.

I've havn't had to brake hard yet, and I did 2 days of easy city driving before going on the highway to brake in the pads.


Anyone else care to give any insight before I go to the mechanic tomorrow?

Reminder : before changing the pads the braking was very good and smooth.

 

New rotors and pads maybe? How long did you break them in for?

 

Maybe you accidentally got some junk on the rotor when you did the pads?

I was just thinking one or more of the rotor faces got something slippery on it and now every time the pad or pads hits that bad spot the friction changes and you feel a modulation.

Just my 0.02

p.s. Turning the rotor means someone machined the faces to clean them up. I think he is suggesting they were machined and got too thin, then hot, and the heat warped them.
Doesnt matter though because you say all you did was swap pads.

 

Like brake fluid or something you mean?

Thanks for the info on "turning". No they weren't turned.

Just new pads. I broke them in for 2 days mild city driving.

IF I need new rotors, could I perhaps use 4 lug Accord rotors? (Integras were never imported here) And if so, would the stock Del Sol calipers fit?

 

TTT

no one can tell me about Accord 4 lug rotors?

No, and no.

For the pulsation problem, try bedding in the pads. This should always be done with new pads, and is especially important when rotors are not changed or turned. Theory and instructions found here.

 

plus I would do a bolt check to see if any of them are loose

 

When I first did brakes on my sol I never had that proplem I put new pads in, what do you know the pedal felt like I had ABS (Which I ******* hate) turns out the rotors needed to be turned. They were SLIGHTLY warped and I mean slightly the old pads must have wore to match them. Got them turned proplems went away.
