1994 Suzuki esteem, this car has been with me since many years and I am driving it with only 10% of power brake 🙁 I have to press the brake pedal really hard to stop the car and if engine is off then its like having no brakes at all.
What my mechanics have tried so far without any success:
Mechanic 1:
———–
Both rear drum facing done on lathe and full service of drum brake.
Front disc facing on lather and brake piston service.
Brake line bleeding to remove any air and fresh oil filled. Dot3 it was.
Brake pads were fine so he just sanded a little and put them as it is.Result: No improvement in brakes.
Mechanic 2:
———–
Swapped the brake booster with other esteem, no improvement. Tried with other booster as well but no result. After 3rd attempt he gave up.Mechanic 3:
————
Found out that my front right wheel bearing is bad and its because of that brakes are not proper. Changed it immediately.
Result: No improvement.Things I have noticed:
Brake pedal is spongy, it goes quite down when engine is started.
On wet surface wheel lock occurs only on left front wheel.

First thing to suspect and replace is the master cylinder. Because they fail a lot and are cheap and easy to replace.
A master cylinder can be bad but not show leaks, this happened to my step dad and he backed out of the driveway one day and didn’t stop, that was a fun 20 minutes back to my house…
Also, be aware that if there is a vacuum leak in the engine, i.e. a loss in intake vacuum, the booster will be less effective since often times that’s where the booster gets its vacuum.
The part throwing me off is that you have a soft pedal when the car is off…
