Loved your video. I used a slightly different approach. I measured the thickness of my rotor at 1.64 mm. Then got out feeler gauges and tried different combinations until I found 1.57 mm thickness. I dropped the wheels out and put the feeler gauges between the pistons of the Shimano 105 hydraulic brake. When I actuated the front lever the brake pistons came in to grip the feeler gauges, causing a slight tightening of the free stroke. This method gave me precise control and works beautifully. Whatever the thickness of your rotor is, use feeler gauges that total .07 mm thinner. If you want even less free stroke, try .09 mm thinner. I think you’ll be pleased with the results.

Nice video and very informative! Instead of squeezing the brake lever incrementally with no rotor present, just put together a credit and, say, a business card (about 1.6mm thickness) and place these between the pads before squeezing the brake fully. if still too much free stroke, remove the business card and repeat with just the credit card. This way you can gradually decrease the free stroke without going too far.

I adjust free stroke by installing a square or 2 of highly sticky 'scotch' aluminium foil to the rear of the pads. This tape is used in the aero industry for similar purposes.. I get the product from a friend who works In the UK and services helicopters for offshore. Used it forever on mechanical and hydraulic pedal cycle brakes.. Its very precise to me and easy.

Concise and very informative! As a v-brake user, I enjoy a very short free stroke on my back brake, and I'm always surprised (and slightly terrified) whenever I find myself squeezing a hydraulic brake lever, and nothing happens for the first 50-60% of the lever's travel. Now that I'm adding a bike with disc brakes to my stable, your procedure will likely be one of the first things I perform on it in order to be able to trust the brakes and love the bike.
@TheBikeSauce

Nice! Thing is the effective pull ratio is different on v brakes vs disc. Whereas you can get a away with very tight v brakes, disc brakes with too little free stroke are subject to disc rub if rotors aren’t perfectly straight

I'm pretty sure this will only work for a while. Once the pads and rotor wear down, the system will begin to compensate normally again. Of course depending on how quickly you wear down the pads, this may last a reasonably long time before you would have to do it again.

Agreed, on the few rides I'd done on bikes with hydraulic brakes I found the excess freeplay rather unnerving. My preference on rim brakes has been to set the brakes up so that the slightest movement of the lever engages the brake. But to transfer to hydraulics, having to hunt around for that engagement point on a brake system with so much stopping power, with a corner fast approaching is a recipe for losing the back wheel or being thrown over the bars. Thank you for this, I've just made the adjustment on a recently-purchased bike.

Your advice acually helped to make the brake at least usable, however I think there is also air in the system, that needs to be removed.

Amazingly helpful video. I haven't done bike maintenance for a couple years now but I just got a new bike that comes with hydraulic brakes installed. Unfortunately the box looks like it got banged up and the front wheel wasn't installed in shipping. This whole time I've been trying to figure out why the tension is way too tight on the front wheel and every video I've watched about hydraulic brakes just talks about caliper alignment. I hadn't heard about this biking taboo about engaging the brakes without a disc but this makes so much sense with hydraulics. The brakes on my bike must've been engaged in transport. I'm going to try resetting the resting point like you showed but now I also have the bonus of knowing about this free stroke adjustment hack!!! Thanks so much. You explain things so well, even for a beginner like me!

I can’t see how this adjustment will hold for more than a short while. The hydraulic system from lever/reservoir to pistons has a very specific volume and, at any point in time, a very specific amount of fluid in it. Partially pushing out the pistons in this way will momentarily expand the volume of the system, but not fluid filling it, effectively inducing a slight negative pressure in the line and reservoir. The only way to get a lasting shorter and firm stroke is to add more fluid to the system by bleeding and filling. I did try the hack on my GRX 600s and all I achieve was a bit of rotor rub and no change to the stroke. I pushed the pistons back and will proceed to a full bleed.

^this. the 'trick' only works till your pads wear back to the starting gap distance, at which point they'll maintain that; as the system is designed to advance pads to a set distance for wear compensation. Maybe you get away with it for some time on a road bike? but on a MTB it'll only last one good ride or two. Ugh, had one hack mechanic at my shop who would pull this garbage instead of real bleeds....

Hmmm...thinking about how the cylinder seals advance with pad wear, doesn't pad wear slowly "undo" your adjustment, to the point where the seal finally rolls forward enough to advance (at the original pad to rotor spacing)? Seems like you'd have to do this adjustment a few times over the life of the pads, and it's basically eliminating one of the advantages of hydraulic disc brakes (i.e. automatic pad wear adjustment)

Thanks for this. It worked beautifully on my GRX 400. Fairly new bike and the factory free stoke seemed too long to me. Now it’s nice and short like I like it. No rotor rub either. This is a good thing to do if you know that your system is new. I don’t like to bleed my system unless I know that it’s time to replace my brake pads as well.👍

...why not just make a shim that's thinner than the rotor?...

Good idea. It might work, but there’s other variables to consider. Also this isn’t an adjustment you should have to make all the time.

@@TheBikeSauce A shim would be more repeatable, though. I tried doing it with a washer that was 0.1 mm smaller than my rotor and that seemed to make a slightly improvement. I'm not sure if I want to push it any more without a better understanding of how the system works. Might try filing it down another 0.1 mm, though.

@@TheBikeSauce I tried filing it down to .2 mm thinner than the rotor. I wouldn't recommend going any thinner than this. There's just a little bit of stroke before top edge of the pad hits the rotor, which is enough to cause drag but not enough to provide any braking force. Now I think the pad to rotor angle actually causes more perceived free play than the air gap.

Oh no, this video isn’t adding any fluid to the system. It’s just tricking the system into thinking it’s got a thinner / thicker rotor. It’s a workaround for not having a free stroke adjustment.

If the Shimano System is as effective as on their MTB lineup, it's useless anyways. Literally nothing happens when you change free stroke on the XT/XTR system.

So in al actuality you are simply reducing pad travel and therefore reducing gap between pad and disc thus causing even more rubbing with less debris on the system. which is already pretty anoying on a GRX brake on gravel. And every little bit the pad wears creates more travel so undoing your work. Up to the point that you're back to the original travel.

Yup. Most of the higher end levers have a knob or adjustment screw to do this for you
@marnixvanderkolk

@@TheBikeSauce sorry but that is not the case. On the high end levers you can adjust the free play between lever and piston as well as the reach of the lever. But that doesn't reposition the pads/pistons in the calliper. There is even a overlap between the two adjustments. But as it is an open system (as opposed to what you mention in the beginning) the piston in the lever has to retract all trhe way to open towards the reservoir. Thus it's not possible to adjust the travel of that piston itself. What you are doing is simply limiting the travel inwards of the pads therefore also the gap between pad and disc potentially causing rubbing or more rubbing and wear af pad and disc. And most of all irritating noise. None of that is done with the adjustment of the high end levers
@TheBikeSauce
@TheBikeSauce 3 жыл бұрын
Sure, but it’s the same effect if you can’t afford high end levers. Not a perfect solution, hence the disclaimers in the video. If you can true disc rotors well, then no rubbing. I’ve had no rubbing on this setup so far and I use this technique on all my bikes. Disc rotor rubbing is irritating, I agree with you
