996 TT Brake fluid?

Not posted on here for a long time, now the proud owner of a 2002 996 TT manual, so time to pick the collective Renn brains once again.

 

Are there any issues with my car running Dot 5 brake fluid? Been doing a bit of reading on it since I found out it has it in the system as opposed to Dot 4 or 5.1 as is common here in the UK. I know Dot 5 is widely used in the US, any issues with it in a 996?

 

Thanks.

Most owners (and shops) tend to stick with the "super" DOT 4 fluids such at the ATE products, which demonstrate very high boiling points, as well as very good all around performance.  Many of the DOT 5 fluids are silicone based for a somewhat higher wet boiling point, but have also demonstrated higher compressibility than other types which has made them suspect for any high performance applications. DOT 5.1 was developed to overcome that shortcoming by switching from silicone to a borate ester/glycol ether or polyethylene glycol while retaining the higher boiling point of the silicone based products, but also tend to be on the expensive side, with a 1/2 liter container approach the cost of a liter of DOT 4.  But by far, the largest selling high performance brake fluid is the DOT 4 type.

We always use Castrol Response DOT4 for normal street use or Castrol RSF for speeders.
