hello
yesterday i change the left side brake disc of my accord 1990.now when i brake the car the brake padel move up and down.plz can any one tell me why its doing that and how to fix this problem.
Thanks

 

You only replaced one side?

What did you replace, the rotor or the pads? Did you bleed the system?

 

yes i replace one side rotor and both thickness are same.the pads i used old ones cuz they are in good shape and i didnt did bleeding so do i need to do bleeding of all wheels?

 

I would just bleed both fronts and make sure you're good. It certainly won't hurt.

Brakes were working fine before the rotor replacement?

 

no the padel was going in because the left side rotor was so rusted it came in 2 pieces.:D

 

Does the padel vibrate or slowly go down when you press the padel?

If it vibrates, that is a problem related to the rotor. If it did not vibrate before you changing the rotor, it might because the old pads can not work very well with the rotor. Give a few days drive and check again.

If the padel slowly goes down, you need to check leaks and bleed the brake line.

 

You should have changed the pad for the left side while you changed the rotor. The old brake pad may be uneven. I would have suggested cutting the right side and change all the front brake pads at that time.

 

Thanks guys i will try:D
