View Full Version : Front brake question

So I have an RG250 bucket(yes, same one that had the back brake problems)

My question is...If I remove one of the calipers and disks to help lighten it, Will I have to change the M/C as well? Wondering about producing too much pressure for one Caliper and the brakes ending up being over sensitive?

So I took the left side off, and there doesn't seem to be any diference in feeling. So it seems I just get a lighter front end with the stopping ability. Sweet

Wouldn't the pressure be simply controlled by how much pressure you put on the front brake lever with your hand?

Yes that's right, same as any braking system, all this radial multicalipered stuff is nonsense. One single piston brake will give you enough braking as anything else. as long as you're superman.

So yeah that was sarcasm. Extreme sarcasm.

Actually simple hydraulic theory indicates that what you have done is lessen the ratio or advantage you have. Feel may be the same as those suzuki fork/antidive thingies if still fitted make everything mushy.

if the brakes were working properly & not seized then you should find they will be considerably less powerful than before but with less lever travel (except you might not notice due to antidive).

Typically you would run a smaller m/c on a single disc setup, say 1/2" instead of 5/8". that might be enough on a bucket. Try taking the line off the antidive & fit it direct to the caliper using the single bolt. blot out old oil from antidive & just leave it there (gets complex to remove). That will give you a more direct feel.

It`s a Ratio , of area of Mcylinder piston to Caliper piston area.As Dave F5 Says. So try it but, you will probably need to go small master cylinder,for same pressure at pad (Same Ratio). Suzuki seem to use smaller caliper piston than most manufacture`s, you may need to go down to 13- 11mm,as used on MX Bikes,for sharp braking.
