Question #1

Can you use solid discs on vented calipers (rear) ?

Question #2

On a V6 model that had vented (rear) discs / calipers would there be any problems in fitting solid discs / solid calipers from say a 2.2

(I know this is considered a downgrade)

Thanks in advance.

Don't do that.

When the pads wear down, the caliper Pistons will quite literally FALL OUT!

...along with the brake fluid and any rear brake performance will instantly disappear.

I think I read that the vented disks were added to help disapate heat from the newer TC system that puts the appropriate brake on the stop slip before any cut in power is used.

So may depend on how much you need TC?

[Mr.OmegaMan]

Can't say I've ever seen the TC light come on apart from a test I did on some grass where it did work.

Reason I ask these questions is because ive got 2 flubbered callipers and I accidentally bought a solid rear brake/pad kit, Was thinking about getting some solid calipers if these's not going to be any major problems.

Anyway I can't find anyone selling Vented rear calipers on eBay usually that Omega Spare Parts place has plenty of stock of everything.

Just weighing my options in this situation.

fixed.
As Chris suggests, there are very good, clear technical reasons why you cannot fit solid discs to vented calipers.

Fitting solid discs to vented calipers is totally and utterly retarded

Merely thinking about such lunacy is completely moronic.

In other words... No. No. And, er, no.

And to answer your second question, the TC on dbw cars is two stage... first cuts fueling, second actively brakes the rear wheels. Solid rear discs won't tolerate getting the shit kicked out of them for very long...

check for sale on here someone was selling a set of calipers and discs

[Mr.OmegaMan]

Well thanks for the confirmation, Always best to make sure 

There's maybe some hope in fixing these calipers, I'll just have to complain and hopefully get these discs/pads refunded or replaced.

Thanks again

Thought the front brake lines where on a differant/seperate "circuit".

Not for long if you're pouring fluid out of both rears, especially if the abs gets involved... it all comes from the same reservoir

[Mr.OmegaMan]

Just to clear something up, I'm not that familiar on how the TC works.

Even though the light doesn't flash in till you actually lose traction does the TC work constantly or only when you lose traction (I.e when the light flashes is the only time the TC is actually doing something?)

Sorry yes, I was thinking more detailed. I'm talking per peddle push. Rears would stop working, each next pump of the pedal would pump more fluid out, but the fronts would continue to work until the fluids gone.

Mine doesn't come on very often unless driving in snow/slippery mush... the light flashing tells you the system is working, but if in doubt, throw the car onto a tight roundabout with it on and then off and you should feel the difference.

I can't remember if it brakes first and then puts the light on when it cuts the fuel, the other way round, or if it does it all simultaneously

Discs and pads, even if vented, are service items and readily replaced with suitable items.
Calipers are usually repairable or exchange ones are available from several sources.


What are you trying to achieve?

[chrisgixer]

He's bought/got the wrong discs, and rightly wants to know if they will work or not.


As they are, somewhere in the region of, 14mm thinner than vented discs, he either needs the correct vented discs to match current calipers, or new thinner non vented calipers to match non vented discs.

[05omegav6]

Either sell the wrongly purchased items to a member who has solid a 2.0/2.2/2.5/3.0 or return them for a refund, assuming that they came from retardsareusECP...
