Irvin85 Posted May 31 Share The brake hose used on Hydraulic brakes. is it one size fits all? For instance will a hose used on a Shimano break work on a set of Formula brakes?

BaGearA Posted May 31 Share Yes and no You might be able to find the appropriate hose at a hydraulics shop but the ends need to be crimped on in about half the cases. Don't know about formula sorry I'm running Sram hoses on my hopes but the fittings screw on and I just cut off the crimped fitting when I bought the hose DieselnDust 1 Link to comment Share on other sites More sharing options...
Martin PJ Posted May 31 Share Formula is brake fluid, so probably Shimano won't work (mineral oil). Try Avid which is also brake fluid, if the size is the same. Link to comment Share on other sites More sharing options...
Martin PJ Posted May 31 Share I see Rapide website sells hose for the Formula and Avid brands, so they are compatible. Link to comment Share on other sites More sharing options...
thebob Posted May 31 Share Get Stoked has spares. Depends on the model you are looking for, but have a look on this link: Brake Accessories & Spares - Get Stoked Link to comment Share on other sites More sharing options...

Barry Posted May 31 Share Hose in most cases has an outer diameter (OD) of 5.0mm and internal diameter (ID) of 2.1mm The XT's use the BH90 hose, which has an OD of 5.0mm and ID of 2.1mm. The RS785s use the BH59 hose with OD 5.0mm and 2.5mm ID (I think? can't find this answer, just know it's slightly larger than the BH90), however many have reported using the BH90s without issue. The only deviation I can find are Tektro and Hayes brakes that use hoses with 5.5mm OD and 2.5mm ID BaGearA, DieselnDust and Irvin85 3 Link to comment Share on other sites More sharing options...

droo Posted May 31 Share Formula have a few different hoses, 2 of which have proprietary fittings swaged on to the end. Check which fitting is on the caliper end and send the photo to whoever you're ordering from so you get the right thing.

David Marshall Posted June 1 Share I have only come across three hose sizes available as "bulk". OD 5mm ID 2.1mm (Shimano BH90), Used in for most Shimano, SRAM and Formula. OD 5mm ID 2.3mm (Shimano BH59). Used in Shimano and Magura MT. Hope has an OD of 5mm and ID 2,4mm OD 5.5mm ID2.4 (Tektro). Used in Tektro, Hayes and Promax. As far as I know all are Dot and oil compatible as long as they are new. Problem as pointed out above is the fittings which are usually crimped on and are brake specific.
