Its very easy to spot the difference if you look at the back wheels and see a disc (just like the front wheels ) then you have disc brakes and if not you have drums
An educated guess: 5 1/2 inch round - this is the case in my 1992 Corolla.
Change front light bulbs
if u do it yourself about 150 for all four. if you take it some where 250 front 300 for the back
Take it to a professional
I need help on fixing my back brakes on my 1997 sunfire
What model of Corolla ? You have to take the dash board out and the bulbs can be removed and replaced from the back. The dashboard on the Corolla is not that difficult to take out, but you have to do it slowly and carefully.
When you have the belt put back on correctly it will be back in time.
First of all, Do you have any specialty brake tools? Ben
To change the front disc brakes on a Kia Rio, simply remove the assembly held by two bolts. Push the piston back and replace the disc brakes with new.
For the front two speakers, you'll need 4". The back two are 5 1/4".
You probably need to change your back brakes.
