Sounds like the perportioning valve is stuck off center and letting to much break bias to the rear and not to the front, this can happend if it has ben run low on fluid, or in break bleeding, if the peddel was pushed to far to the floor.

I have 2002 chrysler grand voyager 3.3 litre auto. abs light came on and is gone now , but there is a lot of vibration and rattle when i press brake. What do i do?


Inspect both the front and rear brakes. Including rotors, drums( if equipped in rear), abs sensors and wiring to the sensors, and brake pads/shoes. Also be sure to remove the calipers and look at the brake pads to check for worn out or uneven wear and replace if necessary. Hope this helps

Replacing caliper on 2002 dodge neon


The first thing is to make sure the caliper piston is all the way in, the caliper then slides over the brake pads and bolts on, make sure you have the correct caliper on the right side, the way to know this is when caliper is on the little bleeder screw should be on the top, if it is on the bottom then wrong caliper, try the other one,

After caliper is on you will then need to bleed the brake system,
This all depends on what happened, if the brake fluid did not all leak out and caliper was just bad then before removing brake hose off old caliper pinch rubber brake line with a pair of needle nose grips or there is a line crip tool that crips hose to avoid fluid from leaking out. this makes bleeding easier , other wise you will need to make sure fluid is full and start at the right rear wheel bleeding and move to left rear then right frt and last left front, you will need to keep an eye on the level of brake fluid and add as need to keep it from going empty,
you will need some one to pump and hold brake while you bleed them, pump pedal three times and hold down while you open bleeder screw, this is to be done to every wheel about four to five time to make sure all air is out . good day. note if pedal feels low bleed again wont hurt anything just a little more fluid lost.

Rear brakes. is there a heat shield or is it a dust shield


If it is in front of the passenger side rear brake, it is a dust sheild installed in an attempt to keep the brake pads from wearing out prematurely. This does not work very well. Do what I do and double the life of your pads. I remove the lower brake caliper stud and flip up the caliper, remove the pads and swap with the drivers side. The drivers side does not wear for some reason, and you will probably have to squeeze in the caliper for the pads to fit back over the rotor. This only takes 4-5 minutes if you do it every 10k miles or so (keeps everything from rusting stuck). I do it to mine when I do a winter tire changeover.

I put new brakes and rotors on my jeep 2000 Grand Cherokee 4x4 and now there is a whine in the front. What can cause this?


If it is only when your foot is on the brake pedal: A lot of new rotors come with a thin layer of wax on them to prevent rust, and so they must be cleaned before the installation with soap and water, and dried thoroughly
If it is only when you apply/release the brake pedal: You need to apply a small amount of grease to the caliper bolts (not the threaded part but the slide pin that is the long smooth part). There is a specific type of grease for this you can get at your local auto parts store.
If it is all the time: Drive around the block, then remove the front wheels and look for a shiny spot on the inside of the rim, or any other components in the area, sometimes the dust plate between the hub and the caliper gets a little bent when you do a brake job, and will grind on the inside of the rim a little bit.

Uneven brake pad wear how do i fix it?


Unless one of your calipers is sticking or not engaging fully then there should be no reason for uneven wear unless you have a defective pad.

There will be uneven wear from the front to the back however. About 60% of the stopping power is provided by the front brakes and 40% from the rear , so your front brakes will wear faster than your rear brakes.

Change back Brake pads on renualt megane 2


1. Hand Brake ON , loosen wheel bolts to hand tight, jack up front wheel , chock back wheels , put axle stands/blocks in place (just in case) .

2. Remove wheel. Disconnect pad wear wire , it pulls out of the connector.

3. Remove lower caliper bolt (at the back of caliper at the bottom) , need a 13mm ring spanner for head of bolt and 17mm to stop it spinning

4. Use a screw driver between the back of the outer pad and the caliper to prise the caliper back away from the back of outer pad. Pivot caliper upwards to rest on top of wheel disc (good idea to tie it up with some wire) .

5. Remove and discard old pads , clean out with wire brush and soft brush , don't breath in to much of the dust its nasty.

6. Fit new pads (remember pad wear sensor on inside pad), make sure that the pads are in contact with the disc , and the top of them sitting flush with the rim of the disc, don't force them into this position they should naturally sit there.

7. Lower caliper down into position, you may need to push back the piston further in order to make room for the new pads , do this with you hands or a small piece of timber. Keep an eye on the brake fluid resivoir , your pushing fluid back in so if its over full it may spill over. Refit lower caliper bolt (Renault say to replace this each time), and tigthen. Reconect pad wear sensor.

8. Pump brake pedal until normal brake pressure returns.

9. Remove axle stand/blocks , refit wheel and bolts , lower jack and tighten up wheel bolts.

Wat tool do i need to remove front and back brake calipers so i can replace brake pads on a audi a4 2002 2.0 se


For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!! For front brake pads. First you must verify yours front brake disc diameter: 280 mm or 288 mm. (On my car y have 288 mm). After that you can buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow: 1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose! 2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper. 3. Now you must thoroughly clean the brake calipers (free of grease). 4. Remove outer brake pad from brake carrier. 5. Pull inner brake pad out of brake caliper piston. 6. Check up the brake fluid level on the reservor, and emptying if neccessary! 7. Push piston back into brake caliper housing. 8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward). 9. Install outer brake pad into brake carrier. 10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm. 11. Install both caps. 12. Insert retaining spring into brake caliper housing. Important: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!! Check brake fluid level and top up if neccessary!!! Please Rate my Response! Thanks!

99 Jeep Grand Cherokee uneven brake wear.


All brakes wear unevenly, no matter the make or model. I have been fixing cars for a job for 50 years and that is a lot of experience. Front brakes are the worst for uneven wear.

Front rims get dirty and back ones stay clean


Hi Joanna, What you are seeing is perfectly normal and occurs on any automobile because the front brakes wear faster than the rear.  Notice that when you step on the brake, the weight of the car shifts forward, putting extra stress on the front breaks.  Next time in a parking lot, notice the same dirty front wheels of other cars.
