Hi I have a 71 Toronado and just wanting to know how to change out my rear drum to disk brakes. I saw a part on Ebay that came of a 74 Eldorado that they said would probably work for a 71 .I hope someone can refer me to a person that has done this before.

 

I don't know if that upgrade has been done before. I'm pretty certain Olds never offered rear disc brakes in the 70s.

 

I am thinking of changing my 71 Toronado rear drum to rear disc brakes. Can some on direct me to site that will show me what parts I will need and how it is done .Roy

 

I merged your 2 threads, there is no reason to have multiple threads with the same question.

 

Rear disc brakes are over-rated IMO. 80-90% of the stopping power comes from the front brakes, especially during a panic stop. The only advantage of disc brakes on the rear is that they are more simple to replace pads / maintain than drums.

 

I'll add that the whole point of a proportioning valve is to REDUCE the line pressure and thus braking force at the rear wheels to prevent premature lockup. You're going to spend $1500-$2000 for a rear disc brake kit and then restrict the line pressure to give you the same braking force at the wheels that the drums did? Think about that.

 

I am thinking about it and have decided to save my $2000 and leave my rear drums alone. Thank you for talking me out of this. It really make sense after you put it like that. lol

 

I believe you're making a very wise decision.

 

Now post some pics of your Toronado, STAT!

 

I would save your money on that too. If you replace everything and properly maintain, the drum brakes will work fine
