Rear Discs
the_big_1 - 1/7/16 at 06:40 AM

Hi Guys,

My car has what I think is sierra rear drums.
The setup is VERY heavy and not a great finish etc, rough welds etc.
I was thinking of scrapping the mounts etc and maybe go to discs?
Does anyone sell the mounting hubs etc and what donor parts would I need?


Cheers!

Disc setup will be heavier than drums, assuming you are thinking of using Sierra components.

The current setup looks like cast welded. Each side weighs about 20KG I guess.

Will be swings and roundabouts weight wise using OE setup. Alloy calipers will be only way to save some and very few have a proficient handbrake mechansim.

How about getting new mounting for current drum setup. Rather than the cast piece?

Have you some pics so we can see what you've got ?

Car is stripped but will take pic of a hub to look at later

Many thanks guys!

I built my MK Indy using the Sierra rear drums from my donor car. I wasn't especially worried about weight I have to say, but they worked fine and I painted the drums to make them look a little better. I would also highlight that the handbrake worked very well too (with a new cable and the donor Sierra handbrake lever.

You can buy alloy handbrake calipers off ebay for an audi, brand new for less than £40 each. they fit with sierra cosworth discs and brackets off ebay.

The hand brake on them is very good but you will need audi handbrake cables and caliper sliders too

Hi All,

This is what I want to improve / replace etc.

Thats the rear upright, looks unconventional? but changing the brakes will not not change that part. May be difficult to mount the caliper though.

That looks it was dragged out of the sea!

Drums are not heavy, see if you can get that remade, mine are not show pieces I put the heavy cast piece into a lathe and removed a whole lot of weight before welding into my upright.
