Question about 1994 Buick LeSabre

1 Answer

1994' Buick LeSabre Stutter

To Start...
I have just aquired this vehicle recently and had noticed that the front brakes worn low and the rotors were in need of replacement....
The car had a slight shimmy which I assumed was from the brake pads slightly catching the worn rotors.... but yesterday....
I was on the interstate doin 75 and when I starting descending a hill the car naturally sped up to about 80... at this point I felt a strong kick and for a second a total loss of power... then another strong kick and I had power again once I had decelerated back below 75mph.... any idea what could be causing this?
Also the Car seems to be building pressure and pushing alot of oil out around the dust cover located by the starter and transmission... when this happens the water in my radiator and reservoir will begin to boil and pour out.... is there a possible link between the to leaks (oil and coolant)? They seem to only happen in unison...
No oil or coolant leaks when idling or town driving... but only during 70+ speeds and only after the kick and loss of power...

I am supposed to be driving this vehicle the 110 miles back home in 3 days from now and I would greatly appreciate any help on this subject....
Thank you for your time,
Josef

Oil and coolant leaks happening at the same time is not good!!

My first impression is a blown head gasket. You need to have the compression checked on each cylinder. If it is a blown head gasket. one of the cylinders will have a low reading. As far as the strong "kicks" and loss of power, it could be related to the oil/water problem. If you can't get the problem solved before you have to head home, I would take it SLOW and EASY going home.

Good luck Loringh

Brakes make a whistle noise when applied and sometimes a low grown or grinding when coming to a slow stop or start.


A grinding or rumbling noise can also be symptoms of a wheel bearing or constant velocity joint in a driveshaft. A worn wheel bearing can also cause a 'whistling' sound (as can a worn CV joint).

A grinding noise with brakes is either worn pads causing metal to metal contact on the brake disk/rotor, or the brake backing plate catching on a spinning rotor ... or a loose/missing anti squeal brake shim (they stop the pads from rattling and vibrating).

However, as you say a mechanic has looked at the brakes and can't find anything wrong .. I think I would begin to suspect a wheel bearing or constant velocity joint on the driveshaft (front wheel drive cars).

Severe wheel wobble when braking on steep decents


It is not wheel wobble but vibration from the front brakes. The front brake rotors have worn unevenly (known as disc thickness variation - DTV) and when this occurs you will get vibration from the front rotors as you apply the brakes and it is especially noticeable when braking on down hill runs. DTV is usually caused by poor alignment of the rotors on the hub. In other words sloppy installation procedures.

You will need to replace both the rotors and brake pads on the front and make sure the business that does the work properly checks the rotor for run out.

My car chirps while increasing speed and when I brake my vehicle.


It is possible that the broken tab is your problem because the tabs keep the hardware from moving, especially when you apply the brakes. To determine if this is the case, remove the tire,brake caliper, brake pads, and hardware. Put one of the lug nuts(or two if needed) back on to hold the rotor in place. Spin the rotor by hand and listen for that chirping sound. If you don't hear it, the hardware is the problem. If you can still hear it, check that metal plate that protects the back side of the rotor to make sure its not bent and rubbing against rotor. Also check that nothing is rubbing on the trans-axle(if its front-wheel drive). If all is well in these two places, the only thing left that spins in that area is the wheel bearing. They usually make more of a grinding or roaring sound but sounds can be tricky.. I am a mechanic for a car rental company and often have to diagnose problems by the sound they make. I hope this info is helpful.

When i first start driving my car, the brakes make a very loud grinding noise. if i press on the brake the hesitate, and push back. this only occurs for a while then the ABS light turns on and the work...


The loud grinding noise may be due to worn pads or brake shoes. I suggest you have all brakes on the vehicle inspected for worn pads, shoes, and possibly worn rotors. The ABS light may indicate uneven brake functioning, so for safty sake, have the brake system checked out.

Rear brakes disc or shoes?


Depends.... look through the wheel and see if it looks like the front. (rotor) if it does then it has DISC brakes, If you canrt see anything, then it has DRUM. most likely it has drum brakes in the rear.

My brakes sound like they are grinding


check rear rotors and front rotors for rust buildup (flahlight helps). does the vehicle shake when you come to a hard stop? You will either need to have a front or rear or both brake job (rotors cut or replaced and new brake pads) If the vehicle is shaking when coming to a stop, its probably your front pads. If your hearing the noise from the rear its the rear pads or it you hear it from the front its the front pads. If there significant rust build up or your pads are low a brake job is recommended.

When i press on brakes i can hear a grinding noise coming from he front end, what could it be?


Brake pads are worn. That noise is the sound of the backing plate for the brake pads hitting the rotors. You will need to replace the pads and probablt the rotors. When the brakes go metal to metal like that it typically destroys the rotor.
