A couple weeks ago the rear brake load regulator started to leak on my 93 V6 so instead of replacing it the mechanic ran new lines from the front to each wheel by-passing the regulator and today found out my rear pads are metal on metal.
My question is does bypassing the regulator put too much pressure on the rear brakes or is it just a coincidence that they are worn down as there was no mention that the rear pads were low when the car was services a few weeks ago.
Thnaks,

My question is does bypassing the regulator put too much pressure on the rear brakes

I am a DIY mechanic with 30+ years experience and not certified. That said, in a word - yes. Furthermore, logic tells me both you and your mechanic would be in hot water if you have an accident and the other party or their survivors can prove your cars brakes were modified and contributed to the accident.

In general terms your brake system was designed so the front brakes take 70% of the braking load and the rear 30% to insure stability in normal and emergency braking situations. The regulator is there to insure that happens, preventing the rear brakes from locking up during hard braking. If that ratio is changed, stability is effected. Consider your worn rear brake shoes as a red flag warning. Is that decision to save a buck worth the possible consequences? Get it fixed correctly.

Recyclers and junkyards are a good source for parts on older cars. TAP Recycling is one online source. Check locally. Oh and FIND ANOTHER MECHANIC. If he was certified, Lord help Canada.
