Beware 981 Brake Pedal Mount Bushing
Discussion
My brake pedal finally succumbed to this well known failure a little over 3 years after manufacture. In 2014 there were a number of reports of brakes locking on completely but in my case it seems to have been a very gradual process that was difficult to detect until extra "engine" braking became evident in the last week when coming off the throttle.
Whilst the Porsche service document attributes the problem to "high temperatures and high humidity" my case would suggest vehicle's age and mileage is also a factor.
So in addition to replacing the bushing, I had to replace front disks, front and rear pads (replacing those that had done around 2,500 miles) and rear caliper piston covers. All very irritating because had Porsche made this issue a recall in 2014 and not a "replace under warranty if owner reports problem" then fixing it would not have been so expensive.
If 981 Cayman and Boxsters (probably 2013 - 2014 manufacture) have not had the new part fitted, I'd recommend owners get it done as a precautionary measure even though Porsche still insist on brake "failure" before doing it under warranty. Porsche allow 1.5 hours for Centres to do the work and the part costs £8.50. The relevant service document is "WM 460855"

Bearing in mind the modified nature of your car, I'm shocked you have the car maintained by an OPC Ralph. All the more so when they force you to replace parts that have little or no bearing on the brake pedal bush failure.
This sounds like another case of an OPC creating work when it's not required.
The bush replacement would have been what ? £200 ?
I imagine your bill came to a figure that was many multiples of that ?
Did you request the old pads/discs back ?
I don't think I said I had used a Porsche Centre and I wasn't forced into anything.This sounds like another case of an OPC creating work when it's not required.

The consequence of the brakes being slightly on all the time (because of the bushing issue) was to prematurely wear the pads so they needed replacing as well as making the rear calipers hot. The front disks had started to show small cracks around the holes, despite cleaning after each track day so they were a scheduled replacement, albeit about 2k miles earlier than expected based on previous experience. I don't need to have parts back from garages I trust.
I don't scrimp on brakes as I do track days and have Donnington, Spa, Estoril, Portimao and Jerez coming up.
I have used Exeter Centre for a number of years and they have installed a few of my modifications but obviously not the engine nor suspension. I use them now just for scheduled servicing.
Anyway the point of the post was to warn 981 owners that they may have a lurking problem and anticipation might save them some money.
I assume that if the effect is obvious any Centre would fix it under warranty, if it is noticeable only now and again, best turn the heater up on the way to the Centre.
In terms of build dates, some were replaced in late 2013 so I think 2013 manufacture and maybe early 2014 manufacture but I do not actually know.

My 2013 Boxster has just started to show signs of this, took it for a long drive today
and ended up needing to hook my foot under the brake pedal to release the brakes!
I have only owned the car 8 months and have no warranty.
You say it is a no recall problem so i am guessing i will need to pay for the pleasure of them fixing it??
Do we have a rough price for this fix??
Cheers

The bush is a few pounds and the fix if under warranty is (as I recall) around 75 minutes labour.My 2013 Boxster has just started to show signs of this, took it for a long drive today

I said i just wanted them to change the bush as eveything points to this. they didnt want to do it without this diagnostic charge, they called me back and said to change the bushes would be £243.
If what everyone is saying is correct that the part is £8.50p this seems a little expensive....even for Porsche!!
What is the consensus on this???
This is all quite disgusting. Under warranty, Centres are allowed reimbursement from Porsche for around 1.25 or 1.5 hours Labour.I said i just wanted them to change the bush as eveything points to this. they didnt want to do it without this diagnostic charge, they called me back and said to change the bushes would be £243.

It is a standard change with a time allowance.
