My car is slowed to the front wheels.

If they are bad clear that yes, or but take them to clean them and extinguish them if they are fine and the tracks are ok you can grease and put again but it is best to change them.

If you changed the brake pads it is because you did not put the indicated ones that usually happens, if the pills are new are very close to the discs if you do not have to check the caliper that does not contract correctly and stay fixed, pump the brake with the car on (without movement) and then disassemble the ring and try to turn the disc and verify if it is the caliper or the pills.

Hi Fredy listening your diagnosis, for maintenance reasons you must replace the brake fluid and teach do a test disconnect the boster of the admission system and test the bearing vehicle does not bas to have brakes but you will realize if the vehicle is stopped or you do not tell me how you ba with that test att Jimenez16r

Look at me personally, 2 similar cases and in both the problem was the boster that remains stuck, trying the empty manger of the boster side along with the BayPass valve if the brakes are released at the time of having this means that the boster is stuck. I hope it is useful.
