Audi TT brakes fitted - need some bleeding advice!!

[Lippo]

Quite pleased with myself - fitted the Audi TT brakes i bought last week for £130.

Quite easy to do. Had a big problem removing the retaining screw for one of the old discs. Took me over an hour to get it out after stripping the Philips head.

I used a hose clamp to prevent any fluid loss, then just bled the front two calipers (I already bled the complete system a few months ago).

Does anyone know the correct sequence to bleed the brakes for a Mk4? I've searched the forum and there's a heated debate as to which caliper to bleed first, but no definitive answer.

BTW, the brakes feel much, much better. Obviously they're still bedding in.

furthest from the master cylinder first

Cheers Stu. Is that the same for all recent Seats?

 

[techie]

Its basically the same for every car.

So it's N/S/R, O/S/F, O/S/R, N/S/F?

So it's N/S/R, O/S/F, O/S/R, N/S/F?

With the master cylinder being O/S/F ( Just in front of driver) - I have always done

N/S/R, O/S/R, N/S/F, O/S/F

Never had problems this way

 

[Lippo]

Cheers Dean0. Going to do it that way.

This is when that rarely used tool - The IMPACT driver is worth its weight in gold.

I picked one up for £5 on ebay and it was the best £5 ever spent. one or two hits and the most stubborn retaining screw has come loose.

Got them from Vince at the TTshop. They're not advertised on the website but if you ring him/email him, he'll tell you what he's got in stock.

As for the pads, the calipers normally come with them in. They were nearly new (plenty of meat left) so I used them. The calipers came from a late Quattro so are mint.

The discs are standard ones just drilled/grooved, nothing expensive.

Just bled the brakes in the order mentioned above. Everything seems ok (touch wood).

Does it work when the head is all chewed up? I tried everything - freezing it with Frostbite (rubbish), brute force (hammer, various screw bits) heaet (butane burner). The last two eventually worked. Made the job literally twice as long as it should have done.

I'll have a look for an impact driver, can't have too many tools!!

 

[air121005]

agree with Deano, its rarely used but when needed an impact driver is a toolbox essential

The good thing is that unlike many tools - an impact driver combines TWIST and SHOCK in one hit. At the very point of impact - you push the bit hard in to the screw, it twists the screw and it shocks the screw loose.

Hammers just shock, screwdrivers just twist (and try to come out of the screw at the same time which chews up the head of the screw)
