Cnc Plazmatics

Thats funny why do they do them for vees but not for cnc magura backins?

Cheers for the surport.

Because we found out years ago (did CNC backings in '99), that grippy pad material with metal backing = too much stress on plastic nipple that holds pad. Fine if you keep your brakes set so that there is not much travel from pad to rim, but the further the piston has to push out before pad engages rim.... the higher the stress on the plastic nipple that holds pad.

All tests showed that metal backing, while feeling more solid, does not actually increase braking power.

good luck getting the plaz pads out. ;)

It's not hard :blink: .

Just put the pads on a baking tray in the oven o like 140-160 degrees. The glue will disintigrate long before anything happens to the pads material, and the material just pulls out the backings (Y) .

Don't leave them, though - i did, and melted my pads :lol: - just stay at the oven and check them every couple of minutes. You'll only be waiting 10 minutes at the most.

Cheers,

Joe.

Not trying to sound like a tit here, but I've done it and funnily enough its just like having plazmatics but the feel on the lever is stiffer. Performance doesn't really change as they're good pads anyway!

Not worth all the extra effort when you can buy reds and cousts which work better in the wet as well as the dry.

Was just about to say... I guess most of the people on here had no idea about trials back then. :)

How did the original plaz alu backings hold on to the slaves, just out of interest? O-ring in groove design just like the kolpen/heatsink design?

I always recomend cnc heatsink reds to every one........best pads ever ........loud...awsome hold....mental power and verry good bite (Y)......better than plaz in my opinion

Ive got the heatsink reds in heatsink vee backings, will this be AS good as the magura? as in loud, mental power and very good bite?

I never got a chance to try Heatsink Reds when I ran a magura (:rolleyes:) but on my vee they were ridiculously good - on par with Cousts I would say

They weren't too loud, which was nice, bite and hold were silly good...

Yes, O-ring. The issue is that you can't use too large an O-ring (squish and twist issues) to absorb stress. Therefore, under sudden high stress (pedal kicks come to mind) situations the reletively small O-ring squishes to point of alumium (no dampening qualities) being the main instrument of pressure (hence, force absorbtion is negated).

They looked cool, and felt great. And under the majority of cirumstances worked great..........but there was enough percentage of time that cofidence in durability/longevity did not leave us comfortable.

For those who read instructions and warnings, they are great.....

Heatsink...if i was to get a pair of cnc backings for my £6 pads would that be ok ?....And would the cnc backings be the same width as power pad backings ( rim to small for frame :) power pad backings are just the write width now though :)

To fit the £6 pads into CNC backings you'll need to trim off about 0.5mm from one end, plus cut back the middle a little. I ought to post some photos on my site showing the mod required. That would show clearly how simple it is!

The pad cavity on the CNC backings has been designed to accommodate all the variety of slight variations in pad lengths due to the Magura backings vs Powerpad ones. As a result the cavity is slightly shorter than some longer pads to ensure a snug fit can be achieved.

Ok Cheers steve..so the width of the backings are the same?
