Will an R1 front master cylinder fit?

Suzuki in their workshop manual says to use brake fluid to lube the piston seals. They also say to use silicone grease on the sliders.

I've done that before and have also used RRG on the seals and multipurpose grease on sliders.

As for the bent slider pin not seen that before.

Have used this on brakes of cars and bikes for many years now, compatible with brake fluid and works very well on slide pins - http://www.partinfo.co.uk/files/XZS120GB.pdf

"brake fluid is hygroscopic by nature so will draw moisture into it on contact so come winter time the salt from the roads gets pulled in under the seal recesses and corrosion starts. this is the main cause of brakes seizing.

RRG is not the only thing you can use. you can also use silicone grease which has a lot more uses such as for rebuilding forks and greasing your foot peg and lever pivots."

Is this the general opinion? I will be reassembling the caliper tomorrow and doing the other one

I use a little red rubber grease on the pistons

what stops the brake pads moving around? ive put them back together but they can both move up and down on the pins when they are assembled. i wondered the same thing when i took them off?

[Chris_SVS]

The springy plate, the other end of the pad rests on another plate on the carrier

[DamoK4]

Should there be springs or something separating the pads or moving them back because they can both move around a bit

[DamoK4]

look at that image the rh pad can move at the bottom but stops on a lip on the moving plate thing at the bottom but the left hand pad can move on the bottom pin to the middle of the pin. is this normal. cant see anything to stop it. To me it seems the pad would always touch the rotor

Looks like I have al the parts in according to that. Had a proper nightmare. Didn’t take both sets of pistons out just took one caliper off and did it. Just gone back to the bike to get the other pistons and caliper off and I’ve obviously got no pressure. All my g clamps are missing to clamp the line up with, tried folding it over and cable tying. Put a bag over the end in case it leaked and still got brake fluid all over the front wheel and rim which I’ve wiped off. Ended up getting ****ed off so just took the caliper off anyway thinking I’ll nip into work and air line it off. No ones there. The one Sunday where no ones in. So will have to try and get the pistons out with some pliers if I can get something to stop it marking them tonight

I don’t want to put the other caliper back on as I’m changing the lines and don’t want any crap in my clean caliper. Also need some new bolts to re attach it as they are a bit tired
