I had sticking calipers on back wheel ,so long rides were harder than usual as brakes rubbing . This sorted the problem instantly with a couple of squirts , stripped pads and sprayed the calipers and pads which removed all the built up gunk and left them shiny brand new . Just had long ride no issues all serviced top job . Easy maintenance and save costly visits to bike shop 10 out of 10

Works if contaminants have not yet soaked into the disc or caliper otherwise isn’t as effective.

I rate this better than the alternative well known brand. Pulls off dirt with ease and no more brake squeel.

Worked just fine for me. Brakes were starting to make a noise, believe i may have got some of my chain cleaner on the discs. Sprayed this stuff on though, gave them a good clean and the noise went. Brakes also felt as though they were a bit more responsive!

Saved me buying new discs

It does what it says, cleans discs. However it doesn’t improve braking or stop shudder or squealing brakes in my experience.

Ok

Used a well known brand. Decided to try Peatys as an replacement. Used it to clean my disc brakes as they very squeaky. After a through clean of both discs and pads they still made that awful noise. Went back to my original brand and repeated the process. The squealing stopped...so make up your own mind.
