The Spyke logo on the lever blade actually gives more grip as it’s engraved.
The Spyke logo on the lever blade actually gives more grip as it’s engraved, but the painted on Spyke logo wears off after few rides.
The brake levers combined with the Spyke caliper results in a rougher lever feel than Any hydraulic brakes I have tried so far,
this is due to the return spring in the caliper, it can really be felt through the lever body & lever, the return spring in the lever can also get rough, so you need to lube the moving parts in the lever to avoid squeaking or other noises,
Rech adjustment, the reach adjustment allows the lever to be adjusted to kids hands.
the reach adjustment is on the lever and not on the lever body as on Ml930&ML940 levers this means the reach adjustments much more reliable, the lever stays in the set adjustment, flex in the lever body won’t affect it, but on the ML930
& ML940 flex effects the adjustment, due to reach adjustment on lever body.
barrel adjuster it fits well into my fingers and makes it very easy to adjust the wire tension.
up and down play in the lever blade
No hinged mount, so you have to remove the grips, but for me this is not a deal-breaker.
Flex in the lever body when braking hard, which also is present in the ML930 levers.
the use of rivet for wire puller was a bad choice, it causes fast wear, and more play, than when they were new, and it already had a lot of play, In my opinion, bearings or bushings would be a better solution. after some weeks of use the lever made some noises, due to the wear, I had to lube the moving parts, it kept getting worse, I continued to lube it regularly
flimsy barrel adjusters, they feel nice to grab and adjust but the play is huge.
.I have used these brakes on 3 bikes, some more than others, until they failed.
No banjo fitting
The brake lever body/Master cylinder flex when braking harder than 50%,which is why the plastic lid & the separator & the Master piston unit to bend or get damaged, and cause leaks, so the lever will be soaked in oil, and oil will spit out through the middle where the plastic lid is.I compared the flexing in the levers on m396&m615 and there is significantly more flex in the m615, if you press the lever blade half way you wont see flex on the m396,but on the m615 you will.
Leaking caused by plastic cover bending upwards, and front and the back is also being pushed upwards but sideways too, causing a leak.
temperature changes, will cause changes to the materials, a minor hit can cause this. the design is clearly flawed.
I had to replace one master cylinder due to failed threads, and I had the leaking issues with the new one too.
Impossible so far to get placement seals/grommets/diaphragms, or just the master cylinder separately.
The cause of failure was certainly not over torquing the screws, It certainly was not a crash that caused it,because I never crashed with this particular brake.
Hinged clamp,no need to remove grips & shifter.
the levers are easy to bend back if you bent them,which I have done on 2 bikes so far.
good braking power,at least if you use Metal pads
it’s not too expensive
it’s not too heavy
no need to take off grips to take off the brake, because of the swing arm clamping mechanism.
The Brake Lever will bend if you crash into a tree(before I upgraded the handle bars i was used to ride on the fuel ex 7 with 720 bars),at low-speed,don’t just let the bike fall on the ground,it can bend the brake lever.
You can of course bend it back with proper tools and technique.
M615 Piston seals: the number written on pistons seals.

The Both brakes are too fragile.
Because the brake lever body/master cylinder is way too flexible and that there is a palstic lid,instead of metal lid,which causes the brake to leak.
I have seen a lot of reviews claiming these brakes are a good value at a low price point.
I agree with the braking power for the money is there, but not the reliability, these brakes are too fragile.
same goes for the other brakes with the similar design, for example, M396, M395, but at least it’s possible to get Reservoir Lid Unit for M396, M395.
