Sram guide r pads SQUEAKING no matter what

I recently bought a new sram guide r front brake and rotor and i bedded the pads in and went for i ride i then washed the bike the day after and thought it would be good to wipe down the rotor with some rubbing alcohol and since then the pads have done nothing but squeak i have light them up with a blow torch but still nothing so i sanded them I have done absolutely everything the only thing that works is jamming them with mud and this keeps them from squeaking but then after a few hours back to squeaking until i jam more dirt into them any help that isnt buying new pads as they are basically brand new

You have contaminated pads or rotor. Probably pads.

If nothing works, you'll have to replace pads.

BTW, where did you came with the idea of jamming the pads with mud? Don't do that.

I've had success cleaning the pads with soapy water, applying degreaser after that and doing some downhill high speed stops until it recovers normal braking power. Try to drag the brake as long as you can. The idea is to heat up the brake enough to burn everything thats on the pads.

If you try that keep in mind that until the degreaser is burnt off, it's going to squeal and braking power will be very low.

In any case, unless you're a cheapskate like me, it's probably not worth it. Pads from discobrakes, which is the brand I usually use, cost 7€ each pair.

i tried this and it worked great for about 2 hours and then it squeaked for a few brake cycles and then after that it was fine again and then started squeaking again for just a few cycles as this has made it alot better should i repeat the process

I wouldn't worry too much if the squeaking is occasional. My brakes squeal like a furious pig if they're wet. No need for rain... sometimes passing through a wet section of road or a small puddle is enough.
