Rear Disc Brake Conversion Kit - 1977 Transam

[1977 Transam]

Hi everyone.

Hoping someone knows where I can get a disc brake conversion kit for a 1977 Transam thanks.

I tried sizing up a Baer Brake kit with 12 inch disc and 4 piston setup but it won't fit the snowflake 15 inch rims.

Any help would be appreciated.

I don't want to change to a low profile rim though to upgrade the brakes.

Need a handbrake allocation in it as well though.

Thanks.

Try this company...www.p-s-t.com. On the home page up the top corner type in this part number: DBKRAFXRD07.
Looks pretty comprehensive.
Good luck.

Thanks Chris.   I'll have a chat to them and see if they will work with the original rims.

Have you considered using bigger drums on the rear instead of a disc conversion?

[1977 Transam]

I haven't thanks.  What would be the benefits over disc please?

Any idea what type I could use to fit into the 15 inch rims?

Larger braking surface which will give you firmer pedal feel and longer life. I am sure the biggest option drum brakes will still fit inside 15" wheels but bonnevista would know better.

One of our forum members, LeighP went this route with his '71 Firebird.  As far as I'm aware, he was very happy with it.  I think it's bought as a kit and basically uses rear brakes from a full size car.  Another advantage of staying with the drum rear would be having no dramas with your parking brake.

Sent Leigh a message, I'm sure he'll get back to you.

Yeah, I used a Master Power Brakes kit that fits new B body Police(HD) finned drums onto the back of my 71.
Simple bolt on mod that leaves you with working Park brake and will fit 15" wheels.
The drums come as a unit with backing plates and brakes etc.....everything brand new. Classic Industries is a reseller of these and I scored a good deal when Classic's were having a sale.



This shows 15" Rally wheels.....they clear.

I went with Chevy C10 drums on the back of the Chevelle.  I found the bigger drums work really well & the park brake holds good.
Fits inside a standard 15" wheel. I think the drums are 11" Looks pretty similar to what Leigh has in the pics.

Thanks for the info on the drum brakes guys.

Leigh were yours 11 inch drums as well please?

I was looking at these yesterday from Willwood.  Waiting to hear back from them about whether they would fit in my rims.

Curious about drums now.  Would they have the same stopping power as the Willwoods?

I'm assuming that the discs would be lighter and stay a lot cooler during operation. 

Still learning about the differences though.
