Pre-MOT Inspection Checklist for Porsche Cayman R Owners
These checks follow this Porsche Cayman R's own most-recorded failure strings, starting with what a tester is most likely to flag on a Porsche Cayman R.
-
the brake pipes — “rigid brake pipes excessively corroded”
Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.
Derived from the DVSA failure strings testers recorded for the Porsche Cayman R. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
