No, just be sure you block the wheels and have the brakes on...Just spray your braking system with cleaner and wipe down. Also use an anti squeaking grease to apply to the backside of the pads. Works wonders for all the brakes you hear squeaking and this is all it needed..

When my car is going fast in i hit the brakes my car shake like it doesn't want to stop. what is it.


It sounds like you have a warped rotor. when you brake it shakes the wheel and throws the abs sensor at the wheel assembly and turns your abs on because it thinks that you are locking them up. Replace rotors and pads and it will solve the issue

Hi Cathy, Have a diagnostic scan carried out on your vehicle. The problem could be with the ABS pump or possibly one of the ABS speed sensors attached on each wheel. Regards John

'97 sunfire pulls hard to the right when brakes applied. Changed pads and rotors on front end and bleed brakes but made no difference. Any suggestions?


When you changed the pads did you notice if one side was worn more than the other? The most common cause of pulling when you apply the brakes is a seized caliper. It won't work and the other does all the braking. Your left caliper is likely seized and needs to be replaced. Hope this helps.

Rear brakes are making an alto sound when pressed lightly and espically in reverse. Is this the rotors?


the braking pads are worn, the noise is coming from the small tip that the brake manufacturer assemble on the pads to let you know when the pads need replacing

How do you replace brakes on 1999 Pontiac Sunfire?


The engine size don't matter except when you order the parts. First you will want to chock the rear tires. This is a front wheel drive, when you jack the front, park wont work. you should also set the parking brake.
You will want a metric socket set and rachet, and a fairly large flat head screw driver.
Remove the wheel.
When you look at the brakes, you should see 2 bolts holding them on, If they have a star shape that looks like a screw driver might fit in it, it is a torx bit, you will need to replace the wheel and go get one. The guy at the parts store should be able to tell you what size.
I'm pretty sure it is going to be a regular hex nut, probably 12 or 13mm.
You can loosen them, but don't remove them yet.

First you need to depress your caliper. This can be done a couple ways.
I just insert a screw driver between the pad and the rotor(the shiny thing that the pads make contact with.) Carefully pry the inner pad slowly away from the rotor. Don't scratch the rotor, you can dig into the pad all you want, your putting new ones on.
Once the inner pad is all the way in, then you can remove the bolts and the caliper will slide out.
Remove the old pads and replace with the new.
Put the caliper back on, make sure you get the bolts tight.
Do the other wheel the same way.
The other way to get the caliper pushed in, by the way.
Remove the bolts, remove the caliper from the rotor, Use a large "c" clamp to depress the cylinder.

P.S. Do not under any circumstances remove your brake lines.

When you are finished with brakes and have tires replaced....

Caution!!! Before you start your car, pump your brakes a few times. Check your brake fluid. You more than likely wont need any, but you should always check it.
Also, do not add brake fluid before replacing pads, the level is going to be higher with new pads.

Back brakes will be similar if it is disc, if it is drum, do your self a favor and have some one else do it or get a service manual. I could walk you thru it, but you need more tools and you have to adjust them....
Better to pay $100 or so and have it done right.

My escape is making a grinding sound, along with pulsating when braking. My husband has replaced the abs sensor, and it is still doing te same thing. Any suggestions what to do next?


The grinding sound when braking is almost surely worn brake pads. If an abs sensor is bad it will set the abs light on. Heres an easy way to figure whether to look at the front or rear brakes first. When braking, take notice as to whether the vibration is felt more in the steering wheel or the seat. If it is more in the steering wheel take a look at your front brakes first, and obviously if it is felt in the seat look at the back brakes first. Both front and rear need to be checked out because the pulsating you are feeling is due to rotors or drums that have been heated up and warped. In order to fix both problems, you most likely will need brake pads and rotors/drums. If you just replace the pads, not only will the pads wear away faster due to the damage to the rotors/drums, but your vibration issue will not go away and infact may intensify.

The light ABS is on aND THERE IS A NOICE ON THE LEFT FRONT WHEEL


These definitely sound related. Need to inspect to see if it's something loose (like a wheel sensor) or the brake pads need replacing, etc. etc...

Yellow DSC and Brake light on... recently changed brake pads


Abs and dsc are related and with the light on these won't work. It is possible that you need to go back to where the work was done to look this over.

Brakes pulsate real hard


That is just the ABS system at work. It is supposed to prevent your wheels from locking which often makes the brake pulsate, especially in wet weather or or snow or ice. The only way to really stop this is to disable to ABS by unplugging it and removing the fuse. This will make the ABS light appear in your dash, but your brakes will stop pulsating.
