S type R brake pedal issue

[Harry24k]

Hi Guys

Ive owned my 2005 STR for about 2 years now and its been a great car, soo much fun, surprisingly good on fuel for such performance and very reliable and practical!

However recently I have an issue with my brake pedal, basically if the car is not running and i put my foot on the brake pedal my brake lights will come on and the pedal

will not retrun all the way back up to make the light turn off so they will stay on unless i lift the pedal the last half inch or so by putting my foot under it and lifting it

when running there is no feel to the pedal, its hard to explain but if i use the pedal as i would in any other car the brakes will come on suddenly like emergency braking

its very hard to brake gradually, the brakes are very strong and stop the car very well and i dont have any abs lights on etc but it seems the pedal takes a couple seconds to return

to back to the normal position when released and like i said there is no feel to the pedal and its extremely hard to brake gradually without the brakes suddenly slamming on!

ive owned soo many cars and never experienced anything like this, I dont know if its the brake booster/servo or brakes need bleeding or something else, I heard that if its the booster 

the pedal gets hard to press and mine isnt like that!

 

Any info and or advice would be greatly appreciated

 

Thanks

hi

Sounds like the brake booster, but normally the brake pedal returns

could be master cylinder though

usually if servo is ok, when you turn engine off, if you press the brake pedal, every time you press it, the pedal should get higher and higher, every time you press the pedal and it should feel hard as well, once the pedal has stopped coming up and feels hard, if you hold your foot on the pedal and start the car, the pedal should drop a bit.

usually when the pedal stays down its the master cylinder,

cheers
