Piernas Flacas Posted February 24, 2023 Share Hi guys, after I replaced my brake pads the front lever is super tight it almost doesn't move and the pads are rubbing too close to the rotor. What should I do? Bleed them to release some oil? Bleed both or just front/rear? TIA. Link to comment Share on other sites More sharing options...
Carmichael Posted February 24, 2023 Share I am no mechanic, but would think that u did not push the pistons in deep enough. You will have to push the pads in deeper into the block. Piernas Flacas 1 Link to comment Share on other sites More sharing options...
Martin PJ Posted February 24, 2023 Share There's two things you can try, put some old pads back with the disc out and slightly push the pads apart with a flat screwdriver. Don't try with the new pads, it may damage them. Second thing is to let out a few drops of oil from the bleed screw. I normally put the new pads in the back, ride them a bit to settle down if it is tight. Older ones put in the front.

The old back ones went to the front. So, should I try and bleed from the caliper or the lever? Link to comment Share on other sites More sharing options...

Shimano ? other ... possibly the model number to date it. "Old" Shimano was bled from the bottom up, and worked very easily. "New" Shimano is bled from the top down.

So my question is more about from where should I let some oil out as suggested. Link to comment Share on other sites More sharing options...
ChrisF Posted February 24, 2023 Share Funnel on the top, and do the normal bleed process. I tried to "just let out the air" last year .... ended up getting a bubble into the system .... ended in a complete re-bleed. Easier to just do it right the first time.

Martin PJ Posted February 24, 2023 Share Bottom bleed screw. You don't let much, drop or two. I have only done this once, it did work. I think the situation you describe can happen when the brakes are bled with slightly worn pads. Then when you put new pads there is too much oil.

David Marshall Posted February 24, 2023 Share Before letting oil out I would push the pistons in with the old pads and fit the brake bleed block. If you can get the block in chances are that you don't need to let any oil out. ChrisF, Piernas Flacas and Dusty 3 Link to comment Share on other sites More sharing options...
thebob Posted February 24, 2023 Share Be very, very careful when pushing the pistons back, especially if your brakes run the ceramic pistons. They break for vokol and there are no replacement parts available michaelbiker, dasilvarsa, ChrisF and 1 other 4 Link to comment Share on other sites More sharing options...
