The thickness could be made up for in compound type and how it wears. Two pads of comparable thickness could wear at vastly different rates or a thinner material could last longer and vice-versa. Just visually eyeballing a friction material isnt enough to deduce it as being better or worse than the other.
The mechanic likely makes a better profit margin on Protex to what he does on Bendix and he has his sales pitch down pat it would appear.
He had other brands too not just selling Protex, that was my choice out of them as they were cheaper and are for the back brakes.
No, you're making statements that you cant back up with anything other than hearsay and possibility.
If you're going to state something, atleast have the ability to back it up.
Now go and read what you wrote to me it seems your doing the same.!!
