It is hard to guarantee any service as a positive outcome when a DIY is asking for advise and a service recommendation on any forum, We only do the best we can to give advice based on the information given. If you don't feel confident in doing the service I strongly suggest and because it has to do with your brakes to have a shop at least diagnose exactly what your problem is and then you can decide if you want to "throw money" for the repair. But keep in mind it is your safety as well if you sell the vehcle you may under law be required to tell the buyer there may be a problem with the brake system.
