Because on the OEM rear wheel brake cylinders on my 2001 RAM 2500 the brake line enters the wheel cylinder at about 30 degree angle. The 30mm cylinder which is the subject of this thread is machined to accept the brake line straight in. Therefore, to mount it, I would have to bend the existing brake lines about 30 degrees.

Ok, I gotcha now. I have not done or even looked at the rear brakes on my 01 - due to having an exhaust brake.

Im suprised the original poster, Whitmore did not mention anything about bending brakelines (he has an 01)

I have excessive brake dust on the front, how much will this cut down on the dust? My brake pedal is really stiff, will this help?

Yes, the 1 ton cylinder will help a lot, it puts quite a bit more braking force on the rear shoes. But you'll still have to adjust them or hit the brakes hard in reverse and verify that they're adjusting properly, just like any drum brake setup.

should i get new shoes for the rear and if so for what truck like dodge or gm since the wheel cylider is gm

No - get the Dodge shoes. You are just replacing the cylinder itself. Everything else stays the same.

ok great and one last ? i think..I have 22" wheels for summer but change back to stock 17" for winter..will the 17" wheels fit over the new bigger hub?:humm:

nuttin changes other than the wheel cylender, its the lil dealie that pushes the shoes out................it all fits inder the brake drum

yes you do need to bend slightly but no biggie man.......its so easy an old man like me can do it

Take a look at the pic in the first post. Youre just replacing the wheel cylinder at the top, The difference is a bigger piston in the cylinder which causes better braking.
