Caliper Bleeder Question, Speed vs non Options

[jim_hoyland]

How can you tell speed bleeders from regular ? I have one with a good size hole that I can blow air through easily and another with a smaller hole that I can barely blow air through.

While bleeding the brakes, I ended up putting the larger holed bleeders in so the fluid come through. I used a pressurized pump that attaches to the resivoir

Speed bleeders have a check valve in them. When you open the bleeder the check valve will not let any fluid out till you push on the brake peddle and will then close when you let off the pedal. It makes bleeding the brakes a one man job. I don't like pressurizing the reservoir because the supply lines from the res. to the master cylinder are designed for static pressure. If you apply too much pressure to the res. it might leak.
