Red Rubber Grease

[leegriffiths128]

Changed brake seals a few months ago but they're in need of an overhaul this weekend as theres absolutely no feel or movement in the brake lever at all - just like an on/of switch at the moment.

Anyhows, I remember Dr Squid recommending red rubber grease a while ago and was wondering exactly where its put (stupid question I know). Have trawled the archives but couldn't find anything.

Also, is it possible to refit the seals if they need to be taken out to clean any crudfrom the rim underneath ?

Thanks everyone.

Hi,
Red ruber grease can be bought from some bike shops (phone ahead) and some car parts shops (Halfords didn't have it last time I checked). Seals can be used as long as they are in god condition (no cracks, perising, and they spring back to shape if squished)

Also undo the brake lever from the master cylinder at the top (should be a lock nut underneath and a flat head screw at the top), and clean the lever and the whole area around it then regrease or use some heavy oil to lubricate the pivot and area again, as if the lever pivot and surrounding area are full of dirt and grit, this can give thesymptoms you are describing.

Cheers jambo.

Do you put the grease around the seal and the groove or does some go on the actual piston also ?

[jambo]

coat the seals in it , put a little on the pistons too, it helps it all slide together nicely again.

Ah yes that stuff is good, also Castrol LM grease is also good I believe

Personally I would not reuse the seals if taken out. Could possibly reuse the dust seals but more often than not if the pistons are sticking the dust seals are more than likely gone. If you are going to be taken the seals out then do it properly ie get new seals .

Do not use castrol LM grease on for the seals and pistons. You'll possible end up with no brakes. You must use a rubber safe grease ie red rubber grease.

Falc you better hope Big Ape does not spot your erroneous suggestion. He has taken umbridge with people posting inaccurate advice in the past. One that suggests a totally inapropriate grease for oil seals on brakes could just see him vent his exasperation! :?

Ah yes but 21QUEST has corrected my mistake and anyone reading this thread will surely see his post.

Ill add a comment in previous post just to keep everyone happy then :roll:
