Brake boosters are supposed to multiply the pedal pressure and apply it to the hydraulic lines with the assistance of a vaccum-fed plunger. Technically.
Practically, it is supposed to stop the car with lesser pedal pressure than originally required. It is quite unusual for your booster to be replaced twice, because brake boosters can be overhauled. By the right mechanic, of-course. In most cases, only the "inner-lining" or "felt" needs to be changed.
Booster failure occurs primarily due to faulty vaccum lines or incorrectly mounted master cylinder/plunger. Check your vaccum lines. Check the mounts as well. Also, bleed your brake lines and check for uneven pad-wear or tandem cylinder play.
Technically, all TATA authorised service centres are supposed to give warranty on the parts for a year or so...so you need to check up on that....
Do take your car to another service station as well for the diagnosis....just in case, for an objective analysis.... |
