I got the F150 hydraulic calipers with e-park brake for 42.00 each off Ebay.
got a PN or year/trim for the F150 calipers?
I got the F150 hydraulic calipers with e-park brake for 42.00 each off Ebay.
If you read here, I bought 2021 F150 calipers from eBay.got a PN or year/trim for the F150 calipers?
Here's the Caddy 8 lug rotor with a 2021 F150 two in one caliper. Both are a lot heavier GVW than my Jeep.
No worries.somehow i missed it, thanks
My 2018 F150 XLT has them too.got a PN or year/trim for the F150 calipers?
Awesome work on the controller. So individual control of each caliper, current sensing in both directions? That sounds pretty damn ideal, then you can program whatever specifics you want from there. Are you handling the polarity reversing for releasing the caliper with that dual relay board?
I've been doing some hunting on the same topic, and there are a couple motor driver shield boards for the Uno that have caught my interest.
Polulu Dual VNH5019 - 12a continuous, 30a peak per channel:
Pololu Dual VNH5019 Motor Driver Shield for Arduino
Video example:
Monster Moto Shield VNH2SP30 Dual - 14a continuous, 30a peak per channel (but this one might be obsolete?):

Tutorial for Monster Motor Shield VNH2SP30
They are set up to control dual motors in both directions, sense current on each channel, and have pretty high current capabilities. It'll be a while, but might have to do some tinkering later in the year
4 wire calipers. For a parking brake there's really no reason to mess with the position sensor portion of the calipers. From the research I've done was that that was overkill for a caliper and unnecessary. 2 Wire calipers combined with input from the ABS system and a PWM have enough variability in the closing speed and response time to work without all the position sensing.Good stuff man. Interesting on the caliper flex even around 5a, I heard the guy say they stall around 15a in that video and made me wonder, because I run relatively small rotor diameters for my tire size. But if the caliper is flexing significantly by that point, meh.
Great find on that standalone dual H bridge controller too. I was seriously expecting there to be a pretty good selection of them in uno shield format, but most seem obsolete and/or expensive. So that standalone you found looks like a better bang for the buck, and more readily available.
Side tangent, are your calipers 2 wire or 4 wire?
On mine I went simple, the switch is down where it's hard to hit by accident and you have to have the brake depressed to enable it. I figured if I ever wanted to use it I would likely be moving and have the brake pedal down.That's some cool logic on the circuit...tapping into the speedo signal could be sweet to avoid any accidental button pushes at freeway speeds.
So one of the additional wires is the output of a hall effect sensor on the caliper motor? That goes with what I had read, what's the second wire? A voltage reference for the sensor?
I agree that watching amperage plus some timers seems completely acceptable in my eyes, though I still find the position sensor intriguing even if I don't have an intended use for it
