Don't get me started ffs!!!!! 😠 That's actually the reason I bought mine when I did. I could already foresee the issue post brexit (and I too think it is an incredibly stupid idea) 2 Link to comment Share on other sites More sharing options...

The Cayman R is mechanically identical to a normal 987.2 Cayman with the exception of different shocks/springs, a remap, and aluminium doors Thank you all for the reply, So just to be clear - is this only for heavy breaking track day events or will this be noticed/help when having a bit of fun on some country roads? or even general hard braking? TIA Sean Link to comment Share on other sites More sharing options...

andygo Posted December 29, 2020 Share Posted December 29, 2020 (edited) After fitting the M/Cyl, i noticed a huge improvement whilst exiting my driveway. Once on the road, the difference is literally like driving a different car. The standard brakes (I have a 20k mile old Cayman S) are appalling by comparison TBH. Google ' I fitted a GT3 master cylinder and wish I hadn't bothered' if you are unsure, lol. Edited December 29, 2020 by andygo Link to comment Share on other sites More sharing options...

Cito Posted December 30, 2020 Share Posted December 30, 2020 (edited) Hi all, I was thinking to order one for my 2.9 (which should fit) and deliver it in Italy (where my parents Sto arrivando!). if anybody wants it and is not in a rush, I can order more than one and bring it over next time I will go home (feb/mar hopefully?). cheers, Andrea Edited December 30, 2020 by Cito 1 Link to comment Share on other sites More sharing options...
Liongolfer Posted February 5, 2021 Share Posted February 5, 2021 I think I got a faulty gt3mc. My mech says they bled all 4 brakes, abs etc and the brake pedal still sits so much lower than my original mc. Sigh... Link to comment Share on other sites More sharing options...

Also, is it purely the height that is the issue or dooes it feel spongy as well? I have not done it myself (because you have to mess around with the servo) but you can apparently adjust the brake pedal height. I therefore wonder whether something has been knocked or adjusted incorrectly Link to comment Share on other sites More sharing options...

My pedal was rubbish until I drove down the road and jumped on the pedal really hard to activate the ABS system a few times. Went back home, bled the brakes again, and hey presto, firm pedal at the top of the travel. Bet your man hasn't done that.. There is nothing involved in the fitting that would alter the pedal hieght or travel. Edited February 5, 2021 by andygo Link to comment Share on other sites More sharing options...

You have air in the system guaranteed 👍 You need someone who can cycle the abs pump electronically. aka PIWIS 😁 Link to comment Share on other sites More sharing options...
andygo Posted February 5, 2021 Share Posted February 5, 2021 (edited) Or can nail the brakes to activate the ABS. Deffo works. But look in your mirror first incase you have a bus on your rear end.. Edited February 5, 2021 by andygo Link to comment Share on other sites More sharing options...
Edmundo2 Posted February 6, 2021 Share Posted February 6, 2021 Got mine fitted about 3 weeks ago.. Instantly noticed the improvement within 50m of leaving the site - Strasse who fitted LWFW/964RS mounts/Wavetrac LSD at same time..Even though these other mods bring a significant different feel the GT3 mc really stood out.. Much better at every speed so far and I've not yet had chance to drive it in grippy conditions.. Link to comment Share on other sites More sharing options...

But look in your mirror first incase you have a bus on your rear end.. When I had mine done my Indy said to me that the correct workshop process involved cycling the ABS pump continuously (piwis) while the brakes were being bled. However some people have had good results form DIYing (I didn't see my thread for details) although even some specialist can cock it up and leave air in the system.

Mavrik Posted February 6, 2021 Share Posted February 6, 2021 No need for cycling the ABS pump with a PIWIS but its easier. A braking system with an ABS pump is essentially the same on most cars (just because its a Porsche doesn't make it special) I DIY'd mine in around 2hrs and just jumped on the brakes half a dozen times to activate the ABS then rebled... I'd guess its not been bled correctly 🤔 Link to comment Share on other sites More sharing options...
swanny71 Posted February 6, 2021 Share Posted February 6, 2021 (edited) Worth noting that the Porsche workshop guide on changing MC says to activate ABS pump with PIWIS only if routine pressure bleeding of the brakes does not work (ie give a firm pedal).

andygo Posted February 6, 2021 Share Posted February 6, 2021 Removing the MC does not affect or disturb the pedal end of things, you just undo the 2 brake pipoes, then the 2 nuts that hold it to the brake servo shell. There is a pushrod embedded in the servo body that slides into the MC as you reinstall. It really is that simple. Of course the recommended method is to use a PWIS but without that, as I said earlier a trip up the road to activate the ABS has teh same effect. There are quite a few reports of this working on the net. Link to comment Share on other sites More sharing options...
