Dual Piston Brake pad compressor

[blue302stang]

I have been looking for something to make compressing the dual piston calipers on our work trucks when doing a brake job. I am working on armored trucks and they have some pretty beefy brakes and am currently using a c-clamp, but it takes some force and time. I found this and was wondering if it would actually be sturdy enough to compress brakes of that size? Has anyone ever used one of these and how sturdy are they?

i own craftsman's dual piston compressor and i can use it as single piston caliper and double piston caliper.... i used it a lot and love it...

the reason is i prefer to use ratchet with socket to compressor it so it will not make my hands hurt myself when try do it with my hands to depress it...

i can use air ratchet to speed it up but must be very careful to make right balance or it can break the piston...

I am looking for something like that strength wise, but the pistons on our trucks require a lot of force to compress, so having to deal with 2 screws is going to be a bit of a pain in the ***. I was looking for something that has either one big screw or the trigger style. I have a feeling that the trigger style isn't going to be able to apply the force needed.

i am understand that you want the brake jobs quick but i just suggest that product which dont hurt your hands...

the trigger is nice but if it will dont compressor because hands will not trigger strong enough. many mechanics in past had problems with hands as artistric problems...

This is as simple and as durable as it gets. I use mine all of the time and works well for me. If you need a little more torque, you can slip a wrench over the handle for more leverage. Some models have a nut welded on the center of the handle for a socket and the handle you choose.

I have that, got it from my SO guy: http://buy1.snapon.com/catalog/item...&group_ID=1682&store=snapon-store&dir=catalog

I actually managed to bend it because I wasn't paying attention to who stuck that caliper piston was since it was on my air ratchet

I have the Mac version similar to the Craftsman that def uses. It works great with an impact. Run one done, then the other. It is less messy because it allows the fluid to slowly fill the resevoir, versus forcing it back and sparaying all over the hood.

thats more like what i am looking for, a single bolt compresses both pistons.

I.. never let it fill up the resevoir again. I open the bleeder and attach a hose that is attached to a gallon that I custom made (punch hole, pressure fit-feed hose through ). I especially take care when doing cars with ABS.

Complicated, but far better than forcing old gunky fluid back into the brake system.

Never force brake fluid back into the system, if needed, get a section of vacuum line that fits the bleeder tight and crack the bleeder open then push the piston back allowing the fluid leave via the vacuum line. The line prevents air from getting into the system, after that top off the fluid, pump the brakes then check the fluid again. I cannot begin to tell of the horror stories and problems due to old fluid let alone the effects of forcing fluid back past dished rubber pistons in the master cyl or having crappy old fluid and gunk contaminating the ABS pump and sensors.

P.S. Also, never use or leave brake fluid unsealed. Brake fluid has hygroscopic properties, meaning it will absorb moisture, even from the air.
