~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Group Buy of Jurid/Brembo pads and Brembo/Zimmerman/Jurid OEM spec discs
I've sourced OEM spec standard discs from GSF who already give the TT Owners Club and TT Forum members a 10% discount. However, due to the volume of forum demand and the use of one specific branch we are able to achieve a better discount.
This is through one specific branch only and not available from any other GSF branch.
These discs are to the same dimensional drawings etc. as the Audi parts but they are a lot cheaper . They are also not drilled or grooved like many aftermarket, so called performance discs. Drilled and grooved discs in the standard diameter and size have less metal due to it being machined away and therefore less thermal mass. In comparison, under heavy braking they will rise in temperature quicker than with standard plain discs that have more metal to store the heat. Drillings do not provide extra cooling due to the direction of airflow - the holes block up with dust. Drilled and grooved discs in the standard size of disc are largely a marketing excercise. For performance - stick with standard plain vented discs with corresponding lower peak temperatures and greater reliability.
Discs of the same size loose heat at the same rate, as that's down to the surface area, so it's more important to reduce the temperature rise. That's why your brakes fade when your discs get thin :wink: . You only need to wear 2mm off the 25mm thick discs and they will fade noticibly earlier and need replacing. Having grooves and drillings, means you loose thermal mass and also means you'll have excess noise and pad wear and risk of cracking at these stresspoint features. That's why rally cars, limited to standard brake disc sizes in their class, use plain vented discs without drillings and grooves.
Modern pads don't tend to gas as much at extreme temperatures, unlike previous technology, so there is little advantage in perforating your discs. Really the only proper way to upgrade the discs is to fit larger discs and calipers at some considerable expense.
Restoring the brake components back to new condition will give you a substantial improvement over worn discs and pads!
The discs shown here are by Jurid (Honeywell) Jurid-Honeywell. The Jurid discs now have anti rust plating on all including internal surfaces and are the standard disc offered here representing the best value/performance combination. Also offered are Brembo and Zimmerman. The Brembos used to be painted on the edges to reduce rust in the non swept area as an addition to the OEM spec but have now been cost reduced to stay competative. The Zimmerman rear are still anti-rust plated I believe. You can always add high temperature paint by masking off the swept area before spraying to add this feature to Brembos but the Jurid now seem the best value.
Brembo, Zimmerman and Jurid are highly respected and of very high quality used in original manufacture. They are less likely to crack and warp under severe conditions unlike cheaper lesser quality discs. I've used Brembo/Zimmerman aggressively on the track at Donnington and although I had problems with boiling brake fluid (my own fault for not changing the fluid ), the pads (Mintex Xtreme at the time) and discs survived fine and gave excellent road stopping performance throughout the rest of their life.
The pads offered here are the Jurid OEM standard Audi pad equivalent but much cheaper :wink: . http://www.honeywell-frictionmaterials.com/ Pads are also available as Brembo http://www.brembo.com/en/Auto/Auto-AM/P ... iglie.aspx
The standard disc wear limits (225/180) are 23mm (25mm new) front and 20mm (22mm new) rear which is the wear limit before replacement. Performance is degraded when they get thin and they are more prone to fade. If your disc rim unswept edge was very proud that's an indication that disc wear needs looking at, but rust build up (which occupies 7 times the space of the metal it replaces) can exaggerate the apparent lip - so tap the brittle rust off off with a small hammer first.

Note: Delivery charges are additional: >25kg £16+ VAT, <25kg £8 + VAT, or less - confirm when ordering. For a full set, this is borderline between the two weight charges so depends on available packaging. All efforts will be made to minimise carrier charges.
You can order any combination of pads or discs - just add them up and add VAT if applicable. The prices will be as listed above but GSF will confirm this with you over the phone when ordering. Other marques can be catered for too, so it's worth asking to see what's available.
If you are interested and want to take part then please PM :!: me with the following details:
Any questions, or for fitting advice, then please ask or post here on this thread .
Note: For pads with sticky film anti-squeal backing it's important to clean and degrease the caliper contact faces with methylated spirit so that the double sided sticky pad film bonds the pad back plate to the caliper properly. The film acts as an antisqueel shim and is the same as standard Audi pads. As the calipers get older the surface may become pitted and the film stick less well. Some pads are now being fitted with a more traditional metal shim because of this. Fitting details can be supplied if needed - just ask
