Yup the issue is with the T - Distributor, a major reason about the braking issue in the Corolla,
On braking it just doesnt locks, it also moves towards the left, (a reason being more force on the left tire.
If uve tested the brakes, sometimes it feels that one of the tires didnt even used the brake, only one tire was locked.
My mechanic told me changing the T- distributor with a kabuli one to with the Japanese corolla helps,.
This is funny, but sometimes it feels like when you lock your bikes front brakes and its suggested not to as it might turn upside down, same feels with the Corolla.
