    in a garage it will vary on price ( best thing is to phone around and get best price/s.) as for doing it yourself, again various prices but its obviously cheaper to do it yourself. its the old saying of how long is a piece of string lol .but first you need to investigate which is giving you problems, good luck with it.... troy

SOURCE: 1996 buick LeSabre runs rough at 50 mph

Sounds like low fuel pressure. i.e. fuel pump, fuel pressure regulator, or fuel filter.

SOURCE: My 2004 LeSabre shakes bad

Actually, changing the front rotors is not that difficult and they are relatively in-expensive. Anytime you change the pads on the front of your vehicle i would recommend having the rotors resurfaced or replaced. Especially if you are getting a brake pedal pulse when applying the brakes. Here is a step by step guide that will help you in removing your Front rotors.

Front brake rotors are warped,if it didn't shake before the wheels were removed, re-torque the lug nuts. If the shake was there before,the rotors either need machined or replaced.

On my 2000 buick lesabre, when I am going 70 - 80 mph and I hit the brakes the car shakes badly. I have read that this car has had tie rod problems, rotor problems and overall steering assembly problems....


if your vehicle shakes when you apply the brakes, your rotors are warped or worn. Replace the brakes and rotors!!Steering system will not cause this!!

Brake pedal vibrate pne the spped and brake apply at 30 mph and below


THis is usually a rotor or drum out of true. Replace or resurface as needed. Rotors need LOTS of thickness to avoid warping, during normal braking. Often it is similar cost to replace rotors and so not resurface old ones...

Thanks for your answer. I am wondering though. If my car was shuddering prior to my replacing the pads and rotors and the shuddering occured only when applying the brakes and usually happened when I braked...


Take a look at all the rotors now since you have replaced them. If you notice any unusal wear on one or more rotors, then i would say either the rotor is defective or the brake caliper is at fault. Even with new rotors it does not mean that they are perfect. They may be out of round or they was cut wrong. The problem would even get worse with a caliper piston trying to stick from time to time. Take a little time and inspect each roter inside and out for any kind of unusal wear. Hope this will help you.

My kia front brakes vibrate and the car shudders


take your car to a brake shop and have the rotors turned if your vibration and shuddering is occurring when you actually apply the brakes.

My 1994 Nissan pickup brakes shudder at low speed


Inspect the brake rotors for grooving and score marks and also look to see if there are any heat cracks, if there is grooving or very little brake pad material remaining replace the brake pads and also two new rotors, it is also possible that it is just a frozen or stuck brake caliper, this would be indicated by an uneven rotor one that has more metal or meat on one side that the other also uneven brake pads indicates an uneven brake caliper application

Front brakes shudder a fair bit when braking, even lightly. There hasn't been any whining of brake pads or anything. I am going to change the pads, but how do I know if I need to replace the rotors?...


It seems now a days that everyone loves to turn rotors, the only reason to turn a rotor is if it is running out, what this means is that
it is moving back and forth and not in a straight line. What a brake tec is suppose to do is place a dial caliper on the rotor and spin it and see if it is running out,if it is then it must be turned,as long as the rotor is not under the mfg min width. Any vibration,pulsing,shudder,
would tell me that it needs to be turned, just wanted to explain the reason behind it. Any other questions please post back as everyone is more than happy to help.
