Anyone convert rear drum brakes to disc?

[Shawn1112]

I’m going to attempt to convert the rear drums to discs on the Regal. Anyone do this on a vehicle?
Im looking at this kit (link below). Looks pretty straight forward. Wondering if my booster, master and proportioning valve can all remain or do any of the 3 need to be changed? Asked on G Body forum but hard to get answers over there as it’s very clicky.

Yea, I just used a wilwood proportioning valve. Then did a few hard stops to dial it in.

If possible can you send link? I had a feeling that had to be done. But a bunch of different ones out there. I was looking at this one

Adjustable Proportioning Blocks With Brake Light Switch

This adjustable proportioning block allows you to run lines from the master cylinder to the block and then to the appropriate wheels. What is neat about it is that it also contains the proportioning valve and brake light switch. This dramatically reduces the amount of fittings needed and...

Did you use a kit for conversion? If not what you use. I know I can use brakes from a older 2wd Blazer. But prefer to have newer shit

I swapped in a 4th generation disc rear. Literally put the rear end in, flare new ends to the calipers, and inline the prop valve by master.

 

[DEEZUZ]

Do you have a combination valce by the master? That needs to go away

 

[Shawn1112]

Not sure what that is. But will look it up and figure it out

 

[EmersonHart13]

ilikemtb999 did his I believe

 

[DEEZUZ]

Combo valve is a big aluminum block under the master. You should have one if car is front disc rear drum.

 

[Shawn1112]

So that goes bye bye and what takes its place?

I swapped 4th gen f body brakes on to my 12 bolt. Was cheap and easy. Rotor is just over 12” and gets you an e brake in the rotor.

 

[Bob Kazamakis]

I think it’s in my build thread but basically you need from the backing plates out off the f-body and it literally just bolts on. I had to shim mine a touch to get the caliper bracket centered over the rotor. I literally used the backing plate from my drum brakes and it was the right amount.

I've done it on a Mustang. I went to a Wilwood adjustable proportioning valve. I used factory brakes off of a newer Mustang, so I switched to the master cylinder that was used from the factory with the calipers I installed.

Man I have like no pictures. They sell brackets to run front LS1 f body brakes as well. They look small behind my 18’s though. One day I’ll attempt brembos

Then they are going to look tiny behind my 24’s
??

 

[Bob Kazamakis]

Only issue is I needed to move them to the front instead of the back because they hit my coil overs when it articulates. Put them on that way to try and make e brake hookup better. No go

 

[Bob Kazamakis]

And fronts which are 12” behind a 18” wheel

 

[DEEZUZ]

If anyone has or acquires stock f body ebrake things I need them

Which parts? I had to order the rubber boots from Australia and got cables from amazon. Brake shoes are on there as well

 

[DEEZUZ]

I need everything. The arms the shoes, everything

 

[Bob Kazamakis]

It’s honestly all real cheap at rock/amazon and stuff I’d rather have new

 

[Bob Kazamakis]

Those fucking rubber bits were like $30 though

 

[HILROD]

If you dont want to change any brake lines you can get a GM style disc disc proportioning valve that will bolt up.

Hmmm, I'm now wondering if I'm going to have an issue with coilovers in the rear. They arent in yet, but are going in asap.
Iirc the listing for the kit said for stock shock locations
