Title: Front brake leave feel - help pls
Post by: Camshaft on 29 August 2013, 10:44:41 am
My front brake lever when pulled in has a series of very small vibrations till it becomes very firm not giving much more movement.
1 of 2 things obviously // Brake Master Cylinder or Caliper Seals
Low pressure at low speed it tends to grab a bit not being very progressive in these situations. When moving along a bit faster I don't notice it.

Any clues at to which end the problem is would be appreciated. Gen 1 Thou.

Another possibility (and easier to sort) is that it might be the lever pivot needing a clean and re-grease.

Spray the point where the brake lever contacts the push rod of the master cylinder with WD40. If that  solves it, remove the lever and lightly grease that point and the piviot as Fazer rider says.. This drys up and corrodes lightly from age and washing causing the symptom you describe.

Spot on, quick squirt with the WD40 all is well. Bit of a relief wasn't looking forward to shelling out for rebuild kits and doing a messy job.
Cheers for the advice  :)
