Adding Brake Assist to PFL?

[fawtytoo]

The FL model with SMT has brake assist. Can this be added to a PFL?

Never heard of it being done.
What is it anyway traction control?

It's exactly what it sounds. When you bring the car to a stop, the brakes stay on until you touch the gas. Handy when you have an SMT and stop on an incline. Especially facing uphill.

There are three driver function to do that:
- handbrake
- left foot on brake
- heel toe

I think that the OP is enquiring about whether the parts can be retro fitted, not whether or not they can perform a hill start.

As a side note, the Mercedes company cars I drive have a similar function.
When you come to a standstill, give the brake pedal a sharp 'tap' and it will hold the brakes on until you depress the throttle. Nice feature and handy too.

I have it on my Lexus. I hate it and never use it because if you wait too long it activates the electronic parking brake. I think they do it this way as a safety feature which is annoying.

I have this feature on my Smart fortwo as they're also semi-automatic. It's very handy. It works quite simply by bringing the car to a standstill with the footbrake. The brakes then stay on (for 2 seconds) until you use the throttle. On the Smart, it's called Hill Assist. On the MR2, it's called Brake Assist.

And yes, my enquiry is whether it can be retro fitted.

It is ´only´ software in the ABS module. Noting mechanical.

You would either need a FL ABS module or a software upgrade.
I suspect that the module is not MR2 specific and the feature inherited from the larger production models.
You best bet is research which models use the same module. It is bound to be cheaper and they may even have had a software upgrade availeble.

The simplest however is swap the ABS module from a FL model on the breakers yard and cross fingers. If it works than done. If not, swap back, no harm done.

On a side note, during the eighties I developed an anti-disc warp custom; not holding the brakes when stopped. Even let it roll the last meter - half meter. Almost a relflex.
Holding the pads pressed to the disc causes heat differences and after a hárd stop could and did warp discs.
Probably not an issue on the lightweight MR2 but on the lardy SUVs of today... Mwah. Best not.

Have it my Merc as well (S213 E63 Estate). Not working though and get a 'visit workshop' message'. As I don't use it, can wait until service time!

Does it matter whether the module comes from SMT or manual?

Not thought of that as a technical reason , but I don't wait with footbrake on. I use the handbrake. Because a pet hate is the brake lights from the tub in front in my eyes while waiting for whatever.

I'm not sure Petrus is on the right track here.

I think you need to do some research, understand which parts are required, and how it actually works.

This is your first step.

[Petrus]

I´d wager it does as the SMT is also linked to the ABS module on hard braking.

Peronally I´d try find a FL module while posting the compatability question on Spyderchat; mány more SMTs stateside.

As stated, I prefer to go on facts rather than assumptions.

Cyclehead is the goto.
