If you ever want to go on a very successful elk hunt for the first time, never a bad idea to call a hard core successful elk hunter who hunted and monitored elk every day for most of his life, just for his opinion.
You may or may not agree with all opinions.
But, if you call Mr. Randy Gross in CA, don't really know if he hunts elk, but he can offer his opinion after taking over his father's Model A Ford cast iron brake business.
Years ago, his father, Mr. Mel Gross recommended & provided bonded brakes on mine ......
they may recommend something different today, not sure ...... but like knee replacement for today's knees ..... (a) depends what type of material is used ...... and (b) depends who does the work.
Failure with (a) or (b) ........ and/or (a) + (b) occurs often; hence, different opinions.
