Toyota C-HR 2018 Hybrid - Rear brake pads worn out faster that front ones - Farhan Chowdhury

Hello, my 2018 C-HR hybrid is at 29.7k miles. During the 30k service, the dealer mentioned that my rear pads are at 5mm. The front ones are still 8mm.

Having done some research online it looks like the rear pads may wear faster due to using the hill hold function or the auto electronic parking brake.

Have any of you guys faced something similar? Just a bit confused as I thought the front ones would be the first to be worn out.

Also when replacing the rear pads should I get the discs done as well? They seem fine with no significant wear or lip.

Many thanks in advance for your help.

Assuming your C-HR is FWD and not AWD, Toyota hybrids tend to wear the rear brakes faster than the fronts because when you apply the brakes:

1. Initial braking is by regenerative braking - the front wheels.

2. Further braking then applies the rear brakes.

3. Harder pedal pressure then uses the front brakes also.

Driven gently, you may notice the rear wheels get dirtier than the fronts from brake dust.

Why do they do it that way? Conserving the Big Anchors for The Perfect Storm (emergency stop)?

If there is any significant advantage, I suppose I could hand craft it using the handbrake.

Actually, thinking about it a bit more, there could be, since I have "captive rotors" on the front, which are apparently a sometimes-fatal pain to replace.

Hmm...my driving style may be about to deteriorate into even further eccentricity.

Why do they do it that way?

Initial braking on the front only is because of power regeneration (FWD). Further braking includes the rears for stability, to stop the back overtaking the front.

Sounds like you have 2 mm of life left in the pads, so no need to change yet. If the disks are less than 50% worn and not lipped or deeply scored/uneven, I would just change the pads when you get round to it.

As the pads are original, if you have owned the car from new you should be able to predict quite accurately when those pads will need replacing !

Many thanks for your response everyone. Yes it is a FWD car. I did not own it from new but I have the full history showing the pads have not been replaced, hence these are the original ones. Yeah I will monitor it and replace it when it is down to 2mm.

About the discs, nothing has been reported by Toyota and from the looks of it, there is no damage or signs of wear on them. I'll still get them to check it again. Thank you again everyone

That will not wear the pads at all. Both Hill Hold and the EPB are only applied when the car is stationary thus no pad wear happens.

It appears the OP put the same question on the Toyota Owners site and got the same answer.

Yes because I was told I'd receive a faster response here. There's literally no harm in posting in 2 places.

It's more of a case of during the release period if you rely on the automatic release system rather than manually releasing.

Assuming a generous original thickness of 12mm, that's at least 4000 miles per mm, so plenty of wear left.

About the discs, nothing has been reported by Toyota and from the looks of it, there is no damage or signs of wear on them.

Front discs should last at least one pad change, in our cars usually around 80 - 100,000 miles. I don't think I've ever needed to renew rear discs. They might need a bit of derusting maintenance with a hammer, old screw driver and a carborundum wheel to hone the business area when you eventually renew the 2mm pads.
