Car shakes really bad when i brake???

[RedAudiomobile]

When i brake at high speeds the wheel shakes really bad. Does this just mean i need new brakes or what?

Also when i push the gas down a little, the RPM's dont go up at all, and i push it more and it still doesnt go up. Then i push it harder and it jumps from 1500 to around 3500-4000. Why does it do this, and what i can i do to make it more smooth throughout the RPMS.

I have a 98 3.8 firebird

Bad shakes is probably warped rotors.

As for the RMP thing, is it just the tach not working or does the car not respond then rocket fast?

Rotors

[jhkcam]

Definately rotors, i had the same problem a while back. They should be able to shave them down if they haven't before already, so it shouldn't cost all that much unless you have to get new ones.

umm, wait on the rotors. I had the same problem w/ my car. I had low power steering fluid. check the fluid level first, before u go buying rotors that u might not need.

[Loochy88]

mine is starting to do the same... not too bad, ill check both things

[JAM]

As sugested check the fluid, sounds like warped rotors though. Hard to tell without me driving it.

For the engine just reving then taking off, sounds kinda strange. Could be any # of things. Fuel pump going out, injectors, short circuit in wiring someplace. Any more detail on that part of your problem?

Trust me it's warped rotors, I have the same problem with my brakes. Nearly all 98's have this problem, it's caused by a manufacturing defect when the rotors get to hot from hard usage and then they warp when cooling. Their condition worsens over time, the longer they go the worse they warp. Shaving the rotors will buy you a year to a year and a half, possibly two years depending on how you drive. I had mine shaved down a little over a year ago and they're shot now, so I have to replace them. Hope this helps

i had same problem it is warpped rotors

Try checking the transmission fluid. My mom had the exact same problem on her dodge grand caravan a while back. It was just leaking fluid from somewhere. Some valves or seals or something like that had to be replaced (sorry about the vagueness, but my mom doesn't give me very good descriptions of automotive problems). It ended up costing about $300.

Im a mechanic. i have to work on that stuff all day. It is the rotors. not the tranny fluid or any of the fluids, it's the rotors

[Kidinthehall2001]

Just don't take it to the dealer to get it fixed...they wanted to sell me brand new ones. And the new ones plus install was gonna be $400...yes i said $400. Cause it "wasn't covered under warrenty"

I said "You keep your rotors, and have a free look at my middle finger"

do what i did....buy front powerslots w/tax and shipping for 275 bucks, spend 30 minutes and install them yourself, and use the other 125 bucks on other stuff bc your problems will be fixed....see my other post about them, i love them and they look cool
