Chevrolet Metro lsi 1.3L 2000

Can anyone help? I have the above vehicle which i have a problem when i brake from about 45/55mph. I get vibration in the brake pedal but at slower speeds the brakes work smooth no vibration at all. I have put on new front brakes and shoes new front brake rotors, re torqued the wheel nuts and the problem is still there. Has anyone else had this problem if so whats the answer please.

Sounds like your rear brakes aren't working, or aren't doing much. It puts all the load on the front brakes, and is warping your rotors because they get too hot.

Radio:
Do a test braking with your manual brake. Watch out not to speed that much. Tell us afterwards.

Also, look what I found on a geo metro review page http://auto.consumerguide.com/auto/used/reviews/full/index.cfm/id/2165

Trouble Spots

Brakes: Vehicle is susceptible to brake-pedal vibrations from warped rotor caused by uneven lug nut torque. (1995)

Brakes: Antilock Brake System (ABS) light comes on, especially in hot or humid weather, due to binding in the ABS motor pack. (1995-97)

Doors: The rear doors may not open from the outside due to a problem with the latch. (1995)

It is easy to over torque the wheel nuts and slightly warp the rotors, according to all data the correct torque for my 2001 is only 45 lbs. usually wheels are torqued to 75 to 100. I had the same problem and replaced the rotors. my opinion

hey, I have the first brake problem et the door problem (wich is pretty boring since I have to go in the hatch to open the door), what can I do?

Hi all! well just letting you all know the problem i had is when i first got the car so i put on new disc drums left and right and new brake pads and shoes left and right on the front two wheels and yes re torqued my lug nuts on all the wheels with a torque wrench set at 45 as per the manual i still have this problem. I can only now narrow it down to two things i need new wheel bearings and or new cv joints, i dont think i need cv joints the car makes no popping grinding no noise whatever. Please keep sending me replys i appreciate it as soon as its fixed ill post a message saying what the problem was as to help anyone else if i can thanks. :smile:

Try to isolate the problem. I mean, you should be sure if the problem comes from the front or the rear brakes. Did you the manual breake test already?. What were the results?

Check your tie rods ends and ball joints too. You may have a deeper problem than you may think. jack each wheel up, and pull, push, and shake it. if it even moves a mm, you have a problem that will cause high speed vibration, and potential loss of control. Make sure everything is nice and tight.

my 92 metro does this too... i can also feel a wobble like somethings out of balance. i have new rotors sitting here but havent installed yet.. hoping that fix it

Hi there, well I did the brake test just using the handbrake and the problem is more noticable, more vibration. Not had a chance to take the rear tires off yet but did change the front drivers side wheel bearings and it was slightly better. The old bearings were totally covered with grease which was black!! Any ideas? :biggrin:

:eek: Man.. if your mechanical skills are not good, I believe it is time to take your car to the cardoc. Grease, oil and all that "slippery" stuff on your brakes is quite dangerous. Many of these products on hot circumstances cristalyzes brake pads and make them unusable. The bad thing reagarding this is that it could happen meanwhile you drive.

For real metrobrother, check it ASAP.

Hi there, well had the rear tires off today and checked the drums and brakes which were fine both sides.The only thing maybe is the bushes on the a frame how much give should there be theres only a little thats the only thing I can think to change that may fix the problem otherwise im stuck!!??

Well think the rear drums are warped because of the previous owner riding the brakes which makes them hot, causing them to warp so a mechanic told me who had seen this problem a couple of times before. Can the rear drums just be rotated?

Amnn.. well.. if somebody did it once, I can't see a reason why it could not be done twice. Kind of weird though. Take it easy with the testing Radio.

Just to let you know put rear drums on today and seems to have fixed the problem. No vibration coming through the brake pedal at high speeds just a very very tiny biting for a short time think everything is just wearing in.I managed to get both drums at Car Quest for only $32 for the pair! everyone else seems to want to charge me $80 each this information for the person with the I think 92 Metro with the same problem. The drums were the problem but had to replace the front rotors and brakes because of the damaged that was caused little old lady driving with one foot on the gas and one on the brake had caused this. Well thanks for all the help and I hope it helps anyone else with this problem.Remember drums and rotors can be warped or damaged that the naked eye cant see.

Well im sorry to say that the problem is still there but a lot of the vibration was corrected by putting the new drums on the rear. I dont know if it needs time for the brakes to bed in or I just dont have the problem fixed? Still remains a mystery.Barteldt did you fix your problem by putting new rotors on? not heard any feedback from you? Well im frustrated think I have replaced everything I can think of im totally stumped!!!! :disappoin :confused: :shakehead
