i installed my booster/ master today it was out of a 99 camaro ls1 and it all went well except that the peddle is stiff as can be and takes all my power to slow me down can not lock up the brakes.
i have a 94 lt1 camaro rear axle disc brakes
car was originally drum so i did the combintation spring change to put more pressure to rear disc i beleive 32 lbs spring rate
could that be the problem or am i missing something when i did this?
87 firebird formula thanks trevor

 

Has any one else had this problem?
