Brakes gone off
My front brakes suddenly decided to not work properly. Very stiff and on one disc it looks like the pads no longer strike the disc square.
I can strip them and put back on. All ok. A few weeks later the same again. Any ideas? Could it be that the calliper is not moving on the sliding pin well enough? |

Also I had to Blast out the holes all the pins/locators go in and made sure everything slid nice. I also pumped the Pistons out a bit and used some ACF50 on them so they were anti-corrosion treated.I've done this for years on my Motorcycles.You can use some clean engine oil. I use a C-Clamp with some Masking tape wrapped on the ends of the Clamp to press the pistons back before refit.The tape is sacrificial to save any contact areas. I always de-glaze my pads when I have them off on a bit of flat paver with some 500/320 grit. After completion/Refit I give all the areas around the Pads and the Discs a clean with Carb/Brake cleaner. This may not cure the problem but it will narrow down possibilities and is good brake maintenance.

Re: Brakes gone off
Could be the caliper pins, could also be the disc bobbins getting crudded up and not allowing the disc to 'float'.
Have a look at the quick video here which explains how to free them off. I do this every year around about now, after the worst of the winter grit / salt has gone. |
